Very impressive!&lt;br /&gt;&lt;br /&gt;Here it is the permanet link to LPOD of 20/Mar/2011:&lt;br /&gt;&lt;a href="http://lpod.wikispaces.com/March+20%2C+2011"&gt;http://lpod.wikispaces.com/March+20%2C+2011&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;PS: Check&amp;nbsp; also &lt;a href="http://asterisk.apod.com/viewtopic.php?f=29&amp;amp;t=23185"&gt;Supermoon Photo Gallery&lt;/a&gt; from APOD's forum!&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-5800749402545586391?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/5800749402545586391/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=5800749402545586391' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/5800749402545586391'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/5800749402545586391'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2011/03/lpod-20mar2011-supermoonrise.html' title='LPOD: 20/Mar/2011 - Supermoonrise'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='https://lh4.googleusercontent.com/-ne1hvX8vJv4/TYZaXqRTT4I/AAAAAAAAAbM/dHOvWR4nyjA/s72-c/LPOD-Supermoonrise20Mar11.png' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-8331962181279937979</id><published>2011-03-20T01:06:00.005Z</published><updated>2011-03-20T20:04:57.721Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Outros/Miscellaneous'/><category scheme='http://www.blogger.com/atom/ns#' term='Lua/Moon'/><title type='text'>Biggest Moon in almost 20 years!</title><content type='html'>This animated (&lt;u&gt;&lt;i&gt;click in the pictures to start the animation&lt;/i&gt;&lt;/u&gt;) GIFs shows the "biggest moonrise" in almost 20 years!

Today I will  talk about life on Earth and the possibilities of life arising in other  worlds far away from ours, as well as the basic conditions a planet  must have in order to support life. I will try to reach several topics  and  make you think, wonder and even speculate about extraterrestrial  life.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;The most accepted theory for the origin of life on Earth is called  “The Primordial Soup Theory” which suggests that life began in an  ancient ocean filled with organic compounds and a primitive atmosphere  mainly constituted by hydrogen and nitrogen. The heat, the ultraviolet  radiation and the abundant lightings triggered chemical reactions that  formed amino-acids, the building blocks of life that make up proteins.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;RNA is generally assumed to be the earliest self-replicating  molecule, which eventually led to the first unicelular organism. Several  millions of years later, photosynthesizing cyanobacteria evolved and  the concentration of oxygen in Earth’s primitive atmosphere rose. The  origin of multicellularity  may have occurred from symbiosis of single  celled organisms, each with different roles in the colonies.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;But these were only the first steps. Then, life exploded on Earth:  plants, animals, fungi, etc emerged and evolved for millions of years  until today.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Nowadays, our ‘blue planet’ is full of life and millions of different  species inhabit our planet. Why Earth is really good for life? Well,  there are lots of reasons but I’ll try to focus on the most important  ones. Liquid water is obviously an important condition, and almost all  the life forms on Earth depend on it. Also, it is a solvent and allows  the interaction of organic molecules (in ice the molecules are trapped  and can’t interact with each other; in water vapor the molecules are far  away from each other and the interaction is difficult). Polarity is  another property of water which makes it an “universal solvent”. Water  can dissolve salts, acids, sugars, as well as gases. Most cell  components including proteins, polysaccharides and DNA dissolve in water  making it the basis of life.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Every planetary system has an “habitable zone” where a planet can  maintain liquid water on its surface. Earth is within this zone as well  as Venus and Mars, but these three planets are very different from each  other! This leads us to one of the most important conditions for life: a  life-friendly atmosphere. Venus has an extremely dense atmosphere which  consists mainly of carbon dioxide, thus the pressure at the planet’s  surface is about 92 times that at Earth’s surface and it generates  (along with other greenhouse gases) a strong greenhouse effect, creating  surface temperatures above 450 ºC. In the other hand, Mars has a thin  atmosphere and no greenhouse effect turning the planet in a big cold  desert. Because Mars’ mass is only 10% the mass of the Earth, it makes  atmosphere retention difficult and the constituent molecules are more  likely to be lost to space when buffeted by solar wind. Here on Earth,  the atmosphere has just the right amount of CO2, keeping the temperature  suitable for life.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Earth’s magnetic field protects us from solar wind and cosmic  radiation which damages our cells. It is caused by electric currents in  the liquid outer core which combined with the planet’s rotation creates   a dynamo responsible for the magnetic field. &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Now we know that atmosphere, mass, a liquid outer core and a right  amount of planetary rotation are also major conditions for maintaining  life.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;However, there are organisms capable of living under extreme  conditions such as high/cold temperatures, high levels of radiation,  high salinity, acidity, etc… These organism are called ‘extremophiles’.  This is amazing because it tells us that life can thrive even in planets  with harsh conditions and perhaps life is not so rare in the Universe  as we may think at first glance.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Most extremophiles are microbes like bacteria and archaens (primitive  bacteria-like organisms) and are thought to be the first organisms on  Earth and they are the most likely to survive to an extinction caused by  a catastrophic event.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Astrobiologists are very interested in extremophiles, as many  organisms of this kind are capable of surviving in environments similar  to those known to exist on other planets or moons of our Solar System.  Some people speculate that Mars may have regions that could harbor  communities of extremophiles as well as in the hypothetical subsurface  ocean of Europa (a Jupiter’s moon). Titan, Saturn’s largest moon (and  the second-largest moon in the Solar System), has a dense atmosphere  mainly constituted of nitrogen and trace amounts of methane and other  hydrocarbons. Cassini spacecraft and the Huygens probe found evidence of  lakes of liquid methane as well as clouds and even rain! There has been  some speculation that methane may have a role similar to the importance  of water here on Earth and maybe some bacteria could live on Titan’s  surface.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Some people believes that life exists throughout the Universe, in  asteroids or other small space junk, in a dormant state until it  encounters a suitable environment. This is know as the “Panspermia  hypothesis”. Panspermia proposes that forms of life like extremophiles  become trapped in debris that was ejected into space after  a collision  between a planet which harbor life and comets or asteroids. This kind of  organisms may travel dormant for an extended amount of time before  colliding with other planets. If the new planet has suitable conditions,  the bacteria becomes active and the process of evolution begins. Of  course, the bacteria would have to resist to high pressures, high  temperatures, radiation, etc. The mechanisms proposed for panspermia are  hypothetical and currently unproven and most scientists remain  skeptical about this.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;But the hundred million dollar question is: extraterrestrial life  exists? Life could have emerged in other planets? The truth is that we  never found alien life or even evidence of it, neither in the Solar  System nor in exoplanets. But this means that we are alone in the vast  Universe? Our little planet is that special and unique for life and  there isn’t another planet capable of support life in the big dark ocean  out there? I don’t think so. &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Why? Well, our galaxy has thousands of millions of stars and there  are thousands of millions of galaxies throughout the Universe, so the  total number of stars in the cosmos is unimaginable! With the discovery  of exoplanets, it is not hard to image that many of those stars have  planetary systems which can have planets capable of harbor life. In  fact, it would be improbable for life not to exist somewhere in the  Universe due to the astronomical numbers of galaxies, stars, planets and  moons.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;With that in mind, Frank Drake formulated his equation in 1961 as a  way to focus on the factors which determine how many intelligent  civilizations may exist in our galaxy. Drake’s equation depends on  factors such as: the total number of stars in the Milky Way, it depends  on the fraction of those stars that have planets, it depends on the  average number of planets that can potentially support life per star  that has planets, it depends on the fraction of those planets that  actually go on to develop life at some point, it depends on the fraction  of inhabited planets on which intelligent life emerges, it depends on  the fraction of those worlds where intelligent beings evolve to be able  to communicate and finally, it depends on the fraction of a planet’s  lifetime that is graced with a technological civilization.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;I strongly advise you to see episode 12 “The Encyclopaedia Galactica”  of the famous TV series “Cosmos” presented and written by Carl Sagan.  In that episode, Carl Sagan obtained from Drake’s equation that there  are 10 civilizations capable of communicate in the Milky Way.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;Of course, no one knows those parameters exactly and they give us  only a hint of the number of technological civilizations in our galaxy.  But remember that the Universe has lots of galaxies! So, even if the  outcome of Drake’s equation is a very small number, that number  multiplied by the estimated number of galaxies in the observable  Universe will probably yield a considerable number of advanced  civilizations in the whole cosmos! And the number of non-intelligent  life has to be even greater!&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;We saw that life is possible outside planet Earth, but how we will  find it? The distances are so great that we can’t send spacecrafts or  probes to other worlds. But we can try to listen.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;There are projects, like SETI, that use radio-telescopes to survey  the stars, looking for radio-signals or messages from another  intelligent beings. Now, you may be wondering how we will understand  their messages, because no one expects that they can speak English or  any other  human language. But there is a universal language:  mathematics. They can send a signal with a series of prime numbers, or  the Fibonacci sequence, or something else that any intelligent  civilization will understand as a message, clearly distinct of any other  natural radio source.&lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt; &lt;/div&gt;&lt;div style="font-family: Times,&amp;quot;Times New Roman&amp;quot;,serif; text-align: justify;"&gt;I hope you enjoyed this podcast.

São visíveis as manchas solares 1057 e 1059 (próxima do limbo). A imagem está invertida horizontalmente e também na vertical, devido ao sistema lente-espelho do Solarscope. A imagem original é com luz branca projectada pelo Solarscope, mas para dar um ar mais "quente e côr mais habitual" à foto diminuí o canal azul e verde e aumentei ligeiramente o vermelho (com o Gimp). Há já bastante tempo que não via as manchas solares visto que o Sol tem andado calmo, mas já se nota um aumento significativo de actividade solar.&lt;br /&gt;----------------------------------------------------------------------------------&lt;br /&gt;Today, the Sun looked like this. I took this photo with my Solarscope and Canon 1000D. The sunspots 1057 and 1059 (near the limb) stand out quite nicely. The image is horizontally and vertically flipped because of the optical system lens-mirror of the Solarscope. The original image is seen in white light, but I managed (on Gimp) to decrease the blue and green channels and increase the red one a little bit to give this color to the solar disk.

The title is "&lt;span class="event-title" style="color: rgb(177, 68, 14);"&gt;Life in the Universe: Odds and Expectations&lt;/span&gt;"; I'll try to talk about everything about life in the Universe (including Earth) and perhaps open a discussion of ideas after it, here in the blog. This is a subject where imagination and extrapolation play a big role, but we should not forget the scientific facts...&lt;br /&gt;&lt;br /&gt;&lt;span style="font-weight: bold;" class="event-details-label"&gt;&lt;/span&gt;&lt;span class="event-description"&gt;&lt;span style="font-weight: bold;"&gt;Abstract:&lt;/span&gt; &lt;span style="font-style: italic;"&gt;This podcast is about the odds of life emerge in our Universe. We will see how extraordinary and improbable is our existence. We will seek for the conditions a planet must have to support life and what are the odds of life arise in such a planet. How would be the contact with other civilizations? Is it possible or it's just fiction? How the extraterrestria&lt;/span&gt;&lt;wbr style="font-style: italic;"&gt;&lt;span style="font-style: italic;"&gt;ls may look like? How we will communicate? In this podcast I will try to answer to this questions and to reach several topics. This questions make all of us wonder, and my intention is to make you wonder beyond the horizon, beyond Earth. &lt;/span&gt;&lt;/span&gt;&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-1207876524741254062?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/1207876524741254062/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=1207876524741254062' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1207876524741254062'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1207876524741254062'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2010/01/365-days-of-astronomy-podcast-4th.html' title='365 Days of Astronomy Podcast - 4th October'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://4.bp.blogspot.com/_DGxhJBZPUVs/S1mx773RWxI/AAAAAAAAAXk/mji9NLjHtsY/s72-c/Screenshot.png' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-6670705908972698557</id><published>2009-12-05T22:02:00.007Z</published><updated>2009-12-05T22:31:23.932Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Outros/Miscellaneous'/><title type='text'>ISS passing close to the Moon</title><content type='html'>&lt;a href="http://4.bp.blogspot.com/_DGxhJBZPUVs/Sxre4RBOk4I/AAAAAAAAAW8/GKrHF5wXG28/s1600-h/moon%26ISS%26Jupo.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5411882960461665154" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 266px; TEXT-ALIGN: center" alt="" src="http://img215.imageshack.us/img215/3439/moonissjupo.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div&gt;&lt;div align="justify"&gt;No dia 27 de Setembro vi que a ISS iria passar perto da Lua e lá fui montar o 1000D no tripé. Quanto a ISS apareceu, tirei esta foto. Somente 1º ou 2º separavam os dois intervenientes no ponto mais próximo. Parecia mesmo que ia contra a Lua!

No dia 27 de Setembro resolvi fotografá-lo. Com binóculos já faz maravilhas aos olhos e no meu telescópio ocupa todo o campo da minha ocular de 25mm. É maioritariamente constituído por estrelas de cor azulada e tem umas quantas cor-de-laranja que fazem um contraste espetacular. Foi uma foto rapinha, apenas um total de 6 min de integração, 2o darks; um objecto a revisitar seguramente.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;The double cluster in Perseus is one of my favourite objects in the night sky. It is an easy binocular target, but through a telescope the view is amazing. In my 8 inch f/5 reflector it fills all the FOV of my 25mm eyepiece. I love the contrast between the orange and whitish-blue of the stars. This one was a quicky, with just 6 min of total exposure, 20 darks; I'll definitely revisit this one!&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-929589747713481328?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/929589747713481328/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=929589747713481328' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/929589747713481328'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/929589747713481328'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/10/perseus-double-cluster.html' title='Perseus Double Cluster'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/StjVMNEQO_I/AAAAAAAAAWE/pIqlVTIE4H8/s72-c/doublecluster_stacked%2Boffset%2BCS4_done.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-3408477763255623521</id><published>2009-10-12T19:42:00.002+01:00</published><updated>2009-10-12T19:52:28.622+01:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Júpiter/Jupiter'/><title type='text'>First Light with the Powermate</title><content type='html'>&lt;a href="http://4.bp.blogspot.com/_DGxhJBZPUVs/StN42jokOMI/AAAAAAAAAV8/J7Q8Ys7Awjc/s1600-h/jupopowerv2_CS4.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5391786057566271682" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 400px; TEXT-ALIGN: center" alt="" src="http://4.bp.blogspot.com/_DGxhJBZPUVs/StN42jokOMI/AAAAAAAAAV8/J7Q8Ys7Awjc/s400/jupopowerv2_CS4.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div align="justify"&gt;Apesar da imagem não estar com grande detalhe, foi a primeira que consegui focar com a powermate, isto porque o seeing por estas bandas não costuma querer colaborar (e a colimação também não deve estar lá grande coisa).

Lá apontei a "bazuca" para o Grande Enxame de Hércules e o resultado foi este. A 2ª imagem é um crop de cerca de 60% da versão "widefield". Clicar para ver em tamanho real! &lt;div&gt; &lt;/div&gt;&lt;div&gt;&lt;div&gt;SVP 8" f/5 + Canon 1000D unmodded&lt;/div&gt;&lt;/div&gt;&lt;div&gt;Lights: 15x25s + 25x30s, ISO 1600&lt;/div&gt;&lt;div&gt;Darks: 10x30s, ISO 1600&lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt;O processamento deste tipo de objectos é bastante diferente e trabalhoso, pois é preciso muitas iterações e cuidado para puxar pelas estrelas mais fracas sem queimar o núcleo e evitar saturar as estrelas. Processado com o Nebulosity 2 e CS3.&lt;/div&gt;&lt;div&gt;---------------------------------------------------------------------------------&lt;/div&gt;&lt;div&gt;Transparecy was not good, so I had to abandon the idea of image a nebula. Then I thought about M13 and I pointed the telescope at it, it was my first try at image a globular cluster. This is how it came out. The 2nd image is a 60% crop of the "widefield" version. Click to viewm in full size.&lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt;SVP 8" f/5 + Canon 1000D unmodded&lt;br /&gt;Lights: 15x25s + 25x30s, ISO 1600&lt;br /&gt;Darks: 10x30s, ISO 1600&lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt;Processing this kind of targets is different and more challenging because when I pulled out faint stars I had to be careful not to burn the core of the cluster.

O eclipse total de Europa por Ganimedes, ocorreu (como é possível ver na imagem) das 1:46 UT às 2:01 UT e a ocultação parcial (31%) das 2:05 UT às 2:17 UT, no entanto não foi possível acompanhar toda a ocultação pois o seeing não permitiu obter nenhuma imagem a partir daí, quase de um momento para o outro ficou bastante mau, não permitindo continuar a acompanhar o evento. Sequência capturada com SkyView Pro 8" a f/10+SPC+barlow 2x, pena ter sido só com 2000mm de focal, mas também o seeing não iria permitir mais. As luas estão resized 400%. Na fase parcial do eclipse vê-se a sombra circular de Ganimedes em Europa (ou será um artefacto causado pelo seeing?).&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;On the 12th, two mutual events of Jupiter's moons were waiting to be caught. The total eclipse of Europa by Ganymede started at 1:46 UT and ended at 2:01 UT (as presented on the image) and the parcial occultation (31%) started at 2:05 UT and ended at 2:17 UT, it was not possible to capture the entire occultation due to very bad seeing conditions, the seeing suddenly got crazy! Captured with SkyView Pro 8" at f/10+SPC+barlow 2x, the focal lenght was only 2000mm but the seeing wouldn't let increase it. The moons are 400% resized. In the partial phase of the eclipse I can see a glimpse of Ganymede circular shadow on Europa (or it is just a seeing artefact?).&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-8218509736351999661?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/8218509736351999661/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=8218509736351999661' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/8218509736351999661'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/8218509736351999661'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/08/total-eclipse-and-partial-occultation.html' title='Total Eclipse and Partial Occultation of Europa by Ganymede'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/SoVFjXoqbRI/AAAAAAAAAUU/Ykut4bQlQM4/s72-c/Ganymedes%26Europa_20090812_eclipse%26occultation.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-1901733693255718561</id><published>2009-08-05T14:22:00.004+01:00</published><updated>2009-08-05T14:36:25.972+01:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Nebulosas/Nebulae'/><title type='text'>M27 v2.0</title><content type='html'>&lt;a href="http://4.bp.blogspot.com/_DGxhJBZPUVs/SnmKwy_9IWI/AAAAAAAAAUM/7vsgpVaDcEc/s1600-h/m27_stack%2Boffset_CS3_doneV2.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5366473001917030754" style="DISPLAY: block;

&lt;/div&gt;&lt;div&gt;Mais uma da madrugada de dia 29. M27, Dumbbell Nebula (Nebulosa do Haltere), foi o alvo. Há quem ache que parece mais com um caroço de uma maçã do que com um haltere, mas, nomes à parte, ela é uma nebulosa planetária, o testemunho da morte de uma estrela que ejectou as suas camadas superiores (através de ventos estelares e pulsações) na fase de gigante vermelha dando origem à nuvem de gás e plasma visível na imagem restanto apenas uma anã branca no seu centro. Os detalhes das fotos estão nas imagens (clicar para ver em maior resolução) e a segunda é um crop da primeira com maior resuloção. Processado com Nebulosity 2 (obrigado Paulo Lobão, pelas dicas) e CS3.&lt;br /&gt;&lt;div align="justify"&gt;---------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;Here is another picture taken on the 29th. M27, the Dumbbell Nebula was the chosen target. It is a planetary nebula, the memory of a star's death. During the red giant phase, the outer layers were expelled by strong stellar winds and pulsations, forming the cloud of gas and plasma seen in the photo, leaving behind a white dwarf at its center. The photo details are written on the pictures (click for higher resolution) and the second image is a crop of the original (first image). Processed wiht Nebulosity 2 (thanks to Paulo Lobão for the tips) and CS3.&lt;/div&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-7388124143471984867?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/7388124143471984867/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=7388124143471984867' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/7388124143471984867'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/7388124143471984867'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/07/mais-uma-da-madrugada-de-dia-29.html' title='M27 - Dumbbell Nebula'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/SnMd2PyVAgI/AAAAAAAAAT8/qxH_pX9Ajes/s72-c/m27_stack%2Boffset_CS3_done.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-8091608734192426268</id><published>2009-07-30T13:48:00.003+01:00</published><updated>2010-01-22T14:29:38.527Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Outros/Miscellaneous'/><category scheme='http://www.blogger.com/atom/ns#' term='Publicados/Published'/><title type='text'>Podcast: A Tour through the Lives of the Stars</title><content type='html'>É hoje!!!

Tive de ficar a pé até tarde, e lá apontei para Júpiter à 2:49 da manhã quando este estava a atingir a altura máxima. Vou comprar uma Powermate 5x para conseguir aumentar o disco do planeta e obter imagens com maior resolução, mas parece que ainda vai demorar a chegar. Foi o melhor Júpiter que já fotografei e é o primeiro deste ano. A quantidade de detalhe visível nesta foto é impressionante! O NEB está claramente com bastante actividade e as zonas e "belts" temperadas estão inundadas de ovais, principalmente no SSTeB/SSTeZ (para saber o que estas siglas significam, ver mais &lt;a href="http://www.skyandtelescope.com/observing/objects/planets/3304326.html"&gt;aqui&lt;/a&gt;). Da direita para a esquerda: imagem original, resize de 150%, resize de 200%. O equipamento usado foi o SVP 8+barlow 2x+SPC900NC+UV-IR block. Processado em Registax 5 e CS3.&lt;br /&gt;----------------------------------------------------------------------------------&lt;br /&gt;On July 16th, at 2:49 in the morning, Jupiter was at its highest and seeing was pretty good allowing me to make a decent capture. I really need a Powermate 5x to use in stable nights, to get a bigger disk and to achieve more resolution. It will be definitely the next thing to buy! This is my best Jupiter so far and it is the first one caught this year. You can see tons of detail in this photo! The NEB is very busy with outbreak activity and the temperate zones and belts are full of ovals, especially the SSTeB/SSTeZ (information on the meaning of the abbreviations can be found &lt;a href="http://www.skyandtelescope.com/observing/objects/planets/3304326.html"&gt;here&lt;/a&gt;).

Demorei mais de duas horas a fazer drif alignment com a SPC e o EQAlign. Mesmo assim, o seguimento não foi dos melhores o que só me permitiu fazer exposições de 25s (e dessas só deu para aproveitar 1/3). Decidi apontar à M8, conhecida por "Nebulosa da Lagoa" (nebulosa de emissão e enxame aberto associado), embora já tivesse passado o meridiano e começar a ficar baixa, bem como o glare da Lua a começar a incomodar. Lá consegui por tudo a funcionar, mas existem alguns pormenores que tenho de corrigir/melhorar, e o resultado foi o acima apresentado. O processamento foi demorado e ainda tenho de me inteirar das técnicas de processamento (o amigo Paulo Lobão ficou de me dar umas dicas). Fiquei bastante satisfeito com o resultado, não estava à espera que só com 10 frames de apenas 25s conseguisse captar tanta nebulosidade, ainda mais a minha Canon não está modificada. Os detalhes estão nas imagens. Espero que gostem.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;br /&gt;This is my Canon's first light! I spent two hours drift alignning with SPC and EQAlign. Even though, tracking wasn't very good, which limited my exposures to 25s. The chosen target was M8, the Lagoon Nebula (emission nebula and open cluster). It had already crossed the meridian and the moon was rising, but I managed to get it right. The result is this photo. I'm still a newbie in DSOs processing but next time I will have some tips given by Paulo Lobão. I'm very pleased with the final result because I never thought I would be able to catch so many nebulosity with only 10x25s subs (and my Canon is unmodded!). Details on the photos. I hope you like it.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-7220398181312111014?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/7220398181312111014/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=7220398181312111014' title='2 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/7220398181312111014'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/7220398181312111014'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/07/m8-canon-first-light.html' title='M8 - Canon First Light'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/SmEUzZEekII/AAAAAAAAASo/mWIfdEPQ0v4/s72-c/m8_v1.0_done.jpg' height='72' width='72'/><thr:total>2</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-3055406411110212458</id><published>2009-07-17T21:27:00.004+01:00</published><updated>2009-07-18T12:21:50.746+01:00</updated><title type='text'>Apollo Landing Sites Photographed</title><content type='html'>&lt;a href="http://4.bp.blogspot.com/_DGxhJBZPUVs/SmDfGSbk5VI/AAAAAAAAASA/dLaMsTn1riE/s1600-h/369228main_ap14labeled_540.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5359528855690601810" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 253px; TEXT-ALIGN: center" alt="" src="http://4.bp.blogspot.com/_DGxhJBZPUVs/SmDfGSbk5VI/AAAAAAAAASA/dLaMsTn1riE/s400/369228main_ap14labeled_540.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div align="justify"&gt;A Lunar Reconnaissance Orbiter (LRO), da NASA, enviou as suas primeiras imagens dos locais de aterragens das missões Apollo.

Por isso, resolvi tentar uma abordagem diferente e fiz uma astrofoto menos convencional. Montei a 1000D no tripé, ajustei o temporizador, subi para cima de um tronco de árvore e...apanhei a Lua (do lado esquerdo, aquela "estrela" é Júpiter). Estas duas fotos de 8s de exposição (cada uma resultado da sobreposição de outras duas, uma com flash e outra sem) foram capturadas às 00h30 UT+1 no dia 9 de Julho.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;I set up my telescope but seeing was very poor, so I grabbed my 1000D, mounted it on the tripod, set a timer and then I climbed a trunk and I caught the Moon (Jupiter is that "bright star" at left)! It can be a new sport, how about name it "moon catching"? Each photo is a combination of 2x8s exposures (with and without flash), at 00h30 UT+1 on July 9th.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-5007704221902282045?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/5007704221902282045/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=5007704221902282045' title='4 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/5007704221902282045'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/5007704221902282045'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/07/moon-catching.html' title='Moon Catching'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_DGxhJBZPUVs/Slel1fwL77I/AAAAAAAAARw/kF7cgfGrS4g/s72-c/mooncatching.jpg' height='72' width='72'/><thr:total>4</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-4746244281476589375</id><published>2009-07-08T19:48:00.007+01:00</published><updated>2009-07-08T20:26:22.033+01:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Outros/Miscellaneous'/><title type='text'>Noite estragada...ou não?</title><content type='html'>&lt;div align="justify"&gt;No dia 6 preparava-me para fazer uma observação e uma sessão de astrofotografia, quando, pouco depois do pôr-do-sol, vejo o céu encoberto por nuvens. No entanto, o céu estava coberto por nuvens que ainda recebiam luz solar, embora do ponto de vista da superfície este já se tinha posto, o que lhes dava um tom laranja, vermelho, rosa, enfim, cada um que decida. A Lua também se juntou à festa, a começar a elevar-se no horizonte.

As duas crateras mais interessantes são Messier e Messier A (o par de crateras na vertical, com forma alongada). &lt;a href="http://pt.wikipedia.org/wiki/Charles_Messier"&gt;Charles Messier &lt;/a&gt;foi um astrónomo francês (1730-1817), responsável pela criação do catálogo Messier, o mais famoso para qualquer astrónomo amador. Aquelas "dobras" no terminador são Dorsa Mawson, Dorsa Geikie e Dorsum Cayeux e são muito bem visíveis com esta iluminação de baixo ângulo. Messier é uma cratera com forma oval e parece ser o resultado de um impacto com baixo ângulo. Logo abaixo, Messier A também apresenta uma forma alongada e possui dois longos e brilhantes raios rectilíneos de 100km, apontados para Oeste. Capturada com SkyView Pro 8" a f/10+SPC+UV-IR block+barlow 2x de 3 elementos. Processado com Registax 5 e CS3.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;Another picture from March 14th, this time the subject is Mare Fecunditatis which surface area is about 326 000 km^2! The remarkable pair of elongated craters is Messier and Messier A. &lt;a href="http://en.wikipedia.org/wiki/Charles_Messier"&gt;Charles Messier &lt;/a&gt;(1730-1817) is the author of the famous Messier catalogue, known by every amateur astronomer. Then, there are several wrinkle ridges close to the terminator, they are Dorsa Mawson, Dorsa Geikie and Dorsum Cayeux which pop out pretty well in this low-sun photo. Messier is an oval formation that seems to result from a low-angled impact. Below it is Messier A that is also an oval formation, forming a remarkable couple with Messier. It has two long rectilinear and bright rays of 100 km to the West. Captured with SkyView Pro 8" at f/10+SPC+UV-IR block+barlow 2x.

Ficou melhor que o &lt;a href="http://astro-andregoncalves.blogspot.com/2009/02/1-dso.html"&gt;1º processamento&lt;/a&gt;, mas o balanço de cores ficou bastante mal, por isso, depois passei para P&amp;amp;B. Usei mais subs e o processamento foi melhor, mas com umas míseras exposições de 2,8s não podia tirar muita coisa.&lt;br /&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;Yesterday, I reprocessed the M42 I took in February 11th, trying to do LRGB. It is better than the &lt;a href="http://astro-andregoncalves.blogspot.com/2009/02/1-dso.html"&gt;first processement&lt;/a&gt;, but the color balance wasn't good and I couldn't fix it.

Enviei a imagem (a anterior, com processamento mais leve) ao Chuck Wood, responsável pelo &lt;a href="http://lpod.wikispaces.com/"&gt;LPOD&lt;/a&gt;, e ele fez este processamento. No entanto, não deu para ser LPOD. Paciência. Eu também tinha tentado este processamento, mas pessoalmente não gostei tanto pois a imagem perde muita naturalidade e fica mais ruídosa. Mas são opiniões subjectivas. Que é que vocês acham? Comentem para eu saber que pensam! O Chuck Wood sugeriu-me compilar as minhas melhores imagens lunares num booklet para distribuir em escolas locais para despertar o interesse na Lua. É uma boa ideia a ter em conta! Obrigado Chuck!&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This is the same photo &lt;a href="http://astro-andregoncalves.blogspot.com/2009/04/cleomedes-e-meio-mare-crisium.html"&gt;as the previous one&lt;/a&gt;, but with an agressive processing to enhance every single detail. I sent the photo (the one with lighter processing) to Chuck Wood and he applied this processing. Even though, it wasn't enough to be a &lt;a href="http://lpod.wikispaces.com/"&gt;LPOD&lt;/a&gt;. I have already tried that kind of processing, but I didn't like it very much because with the enhancement of detail, the noise is higher and noticeable and the photo looks less natural. But I think it is a personal preference. What is yours? Comment this post to let me know! Wood also suggested that I should compile my best photos into a booklet which I could give to local schools to encourage an interest in the Moon in Portugal. I will think about that.

Este mostra o anoitecer no Mare Crisium. Metade já está na escuridão enquanto a outra metade ainda permanece visível. Esta imagem com o Sol baixo, revela Dorsum Oppel em todo o seu esplendor. Dorsum Oppel é a "dobra" que percorre quase toda a extensão da fronteira do Crisium. As três crateras no seu interior são, da direita para a esquerda, Swift, Peirce e Picard. A outra principal formação visível nesta imagem é a cratera Cleomedes, logo acima do Crisium. A sua montanha central ergue-se ligeiramente desviada do seu centro e no seu interior as crateras Cleomedes B e J formam um par interessante.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;(Click for full size!) Another two frame mosaic, captured a few minutes after &lt;a href="http://astro-andregoncalves.blogspot.com/2009/04/um-passeio-numa-regiao-lunar.html"&gt;the previous&lt;/a&gt;, with the same setup. The night in coming at Crisium's...in this low sun view, Dorsum Oppel stands out pretty well and runs parallel to almost all Mare Crisium's border. The craters Swift, Peirce and Picard spoil the smothness of the rest of Crisium. The other main feature is Cleomedes whose central mountain peak is still catching some sunlight.

Esta imagem é a composição de duas. Notam-se as margens do mosaico, mas não me preocupei em retirá-las pois a imagem de cima está muito menos definida e serve só para dar mais campo visível. Não foi possível obter o detalhe com igual qualidade à parte de baixo pois o portátil estava a ficar sem bateria e só tive tempo de fazer um avi de poucos segundos. Apesar disso, e muito devido à frame de baixo, penso que ficou uma bela fotografia lunar. Fiz um GIF para legendar o que "salta mais à vista" ou que parece ser mais interessante, mas há outras partes com interesse que não estão legendadas. O telescópio que usei foi o SkyView Pro 8" com SPC+UV-IR block+barlow 2x APO. Capturada às 01:12 UT, do dia 14 de Fevereiro de 2009. Processado em Registax 5 e CS3. De seguida apresento uma breve descrição dos itens legendados. A fonte de informação foi o Virtual Moon Atlas.&lt;br /&gt;&lt;br /&gt;&lt;em&gt;Janssen (walled plain):&lt;/em&gt; Formação circular danificada. Com as crateras Janssen H, K e L a este (direita). Contém Rimae Janssen.&lt;br /&gt;&lt;em&gt;Rimae Janssen (rede de rilles):&lt;/em&gt; Sistema de rilles ramificados com um principal orientado Sul-Norte.&lt;br /&gt;&lt;em&gt;Fabricius (cratera):&lt;/em&gt; Formação circular, com paredes elevadas.

The boudaries of them are visible but I did not bothered with that because for the upper image I only had time to capture an avi of few seconds, so it is not smooth and crip like the other. The bottom image is pretty well detailed because it was the first avi taken and I still had battery in my laptop. Despite the "failed avi" I think it came out pretty good. With SkyView Pro 8" and SPC+UV-IR block+barlow 2x APO. Captured at 01:12 UT, on February 14. Processed in Registax 5 and CS3.&lt;br /&gt;&lt;br /&gt;&lt;em&gt;Janssen (walled plain):&lt;/em&gt; Damaged circular formation. Very tormented floor with the craters H, K and L to the east. Contains Rimae Janssen.&lt;br /&gt;&lt;em&gt;Rimae Janssen (rilles network):&lt;/em&gt; System of ramified rilles with a main South-North oriented groove.&lt;br /&gt;&lt;em&gt;Fabricius (crater):&lt;/em&gt; Circular formation, high walls with terraces. Flat floor with two rectilinear and parallel mountain chains.&lt;br /&gt;&lt;em&gt;Metius (crater):&lt;/em&gt; High walls with terraces suporting two craterlets to the North-West. Flat floor suporting Metius B to the North-East. Small central mountain.&lt;br /&gt;&lt;em&gt;Brenner (crater):&lt;/em&gt; Very damaged formation, little differentiated.

Com as imagens dessa composição o colega do &lt;a href="http://albedo.gem51.com/viewtopic.php?f=32&amp;amp;t=2337"&gt;Fórum Galáctica&lt;/a&gt;, Filipe Dias, fez esta animação com as posições de Vénus e Terra no sistema solar nas datas correspondentes à captura das fotos. Penso que ficou espetacular! As datas estão na imagem. Clicar na animação para ver!&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;I made &lt;a href="http://astro-andregoncalves.blogspot.com/2009/04/venus-season-evening-apparition-09.html"&gt;this composition &lt;/a&gt;that shows pretty well how Venus evolved during that evening apparition. Then, with the images I took, a GIF was made by Filipe Dias with the positions of Venus and Earth in the dates I took the corresponding photograph. I think it came out really well! All the photos were taken by me, with a 8" reflector at f/10, a SPC900NC and a barlow 2x, in Vieira do Minho, Portugal. The dates are on the pictures.

A imagem está um pouco escura e o centro das galáxias está sobreexposto, mas foi o que saiu por agora. Continuam a aparecer "sombras" à direita das estrelas e nos centros galácticos, não sei a que se deve este efeito, se é alguma coisa que está mal ou se é defeito da câmara. Tenho de fazer mais experiências...para já, fica a primeira M51, por volta de 50x25s frames.&lt;/div&gt;&lt;div align="justify"&gt;--------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;In the same night as the &lt;a href="http://astro-andregoncalves.blogspot.com/2009/04/1-galaxia-m82.html"&gt;previous M82&lt;/a&gt;, taken with the same equipment, I also moved the telescope to M51, the Whirlpool Galaxy,  and took this photo (about 50x25s, not sure). The picture looks to dark and the cores are burned but I still dont know much about the processing. I dont know why did those "shadows" at the right of the stars and cores appear; if I did something wrong or if it is a problem of my DSI.

Para apanhar as luas tive de aumentar o ganho e o tempo de exposição, que ficou em 1/25s, o máximo que a SPC permite. Claro que Saturno ficou sobreexposto por isso tive que trabalhar as luas e depois adicionar Saturno noutra &lt;em&gt;layer, &lt;/em&gt;por cima do anterior (sobreexposto), no Photoshop CS3. Da esquerda para a direita, as luas Dione, Rhea e Titã, de magnitudes 10.4, 9.8 e 8.4, respectivamente. Não estava à espera a SPC conseguisse "ver" outra lua para além de Titã, mas já deu para perceber que tem um CCD bastante sensível.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This is the same Saturn &lt;a href="http://astro-andregoncalves.blogspot.com/2009/03/saturno-ainda-perto-da-oposicao-2009.html"&gt;as before&lt;/a&gt;, but with moons added. To catch the faint moons I had to increase the gain and the exposure time to 1/25s which is the maximum that the SPC allows. Of course that Saturn was overexposured, so I worked on the moons and then added the good Saturn in other &lt;em&gt;layer.&lt;/em&gt; From the left to the right, the moons, Dione, Rhea and Titan with magnitudes of 10.4, 9.8 e 8.4 by the same order. I wasn't expecting to catch moons fainter that Titan but here they are! I guess that SPC has a pretty sensitive CCD.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-3876775139556939242?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/3876775139556939242/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=3876775139556939242' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/3876775139556939242'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/3876775139556939242'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/04/saturno-versao-com-luas.html' title='Saturno - Versão com luas'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sdf7Yr5bPGI/AAAAAAAAAPo/5rAmFBiIn1I/s72-c/Saturn_3moonsCS3.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-6435895847668465432</id><published>2009-04-02T18:02:00.004+01:00</published><updated>2009-04-03T20:41:13.132+01:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Galáxias/Galaxys'/><title type='text'>1º Galáxia - M82</title><content type='html'>&lt;a href="http://4.bp.blogspot.com/_DGxhJBZPUVs/SdZh7bTuGEI/AAAAAAAAAPg/FjExtpIKFyE/s1600-h/M82c_CS3.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5320547683355465794" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 287px; TEXT-ALIGN: center" alt="" src="http://4.bp.blogspot.com/_DGxhJBZPUVs/SdZh7bTuGEI/AAAAAAAAAPg/FjExtpIKFyE/s400/M82c_CS3.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div align="justify"&gt;Aqui fica a minha primeira galáxia. Capturada no dia 23 de Fevereiro entre as 3h-3h26 UT com o SVP 8" e DSIc em &lt;em&gt;prime focus&lt;/em&gt;. Cada frame teve 20s de exposição, sem guiagem. Ainda não domino totalmente o processamento deste tipo de objectos e houve uns pequenos problemas com a câmara e guiagem, mas fica aqui o resultado que não me desagrada. A M82, também conhecida por galáxia cigarro (Cigar Galaxy) devido à sua forma; é uma galáxia irregular vista de perfil. Tem uma alta taxa de formação estelar (é uma &lt;em&gt;starburst galaxy&lt;/em&gt;), comparativamente à maioria das outras galáxias. Processada com MaximDL e CS3.&lt;/div&gt;&lt;div align="justify"&gt;---------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This is my first photo of a galaxy. It was captured on February 23th between 3h-3h26 UT with my SVP 8" and Meade DSIc in &lt;em&gt;prime focus.&lt;/em&gt; Each frame is a 20s exposure, unguided. I still haven't figured out all the details about processing DSO's, but I liked what came out. M82, is known as the Cigar Galaxy due to its shape; it is an irregular galaxy that is seen edge on from our line of sight. It is a &lt;em&gt;starburst galaxy &lt;/em&gt;which is a galaxy with an high rate of star formation.

O seeing estava bastante bom, o que permitiu capturar uns quantos frames com bastante detalhe. Várias bandas atmosféricas são facilmente vislumbradas e a variedade de cores é grande. Apesar de várias bandas serem visíveis, as que mais sobressaem são a esverdeada no hemisfério norte, a zona equatorial amarela e a banda vermelha no hemisfério sul. Outra característica facilmente observável é o brilho dos aneis e a sua pequena inclinação, bem como a sua sombra no disco de Saturno. Pedia mesmo mais amplificação nesta noite tão estável...preciso de arranjar uma Powermate 5x ou outra barlow do género, para conseguir os planetas maiores. O da esquerda é o original (a f/10) e o da direita está &lt;em&gt;resized&lt;/em&gt; 150%. Foi capturado no dia 14 de Março pelas 00h40 UT, apenas 6 dias depois da oposição e com um diâmetro aparente de 19,85". Com SVP 8"+SPC+UV-IR block+Orion ShortyPlus 2x APO. Processado com Registax 5 e CS3.&lt;/div&gt;&lt;div align="justify"&gt;--------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This is my best attempt to Saturn so far (I guess). Seeing was great, so I could be able to capture several atmospherical banding with many colours. The most eye-catching bands are the green in northern hemisphere, the red in the southern and the yellow of the equatorial zone. Notice the bright rings compared with the darker disk, the small tilt of the rings and its shadows on Saturn's disk. The seeing in that night asked for more magnification but cannot go behind f/10 with the actual equipment, I really need a Powermate 5x or a barlow of that type to get bigger planets and lunar close-ups. At left it's the original and at right it's the same photo &lt;em&gt;resized&lt;/em&gt; 150%. Taken on March 14 at 00h40 UT, just 6 days after oposition, with an apparent diameter of 19,85".

Eram 19:28 e a Lua estava poucos graus acima do horizonte, em plena luz do dia. Reparei nesse cenário e num pequeno barco à vela que ia a passar nessa altura e achei que era uma combinação perfeita. Aqui ficam os resultados.

At 19:28 the moon was just a few degrees above the horizon, in broad daylight. At that time, a little wind sailing boat was crossing the area and I thought that it made a wonderful combination.

Espero que oiçam.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;I'm glad to annouce that I "won" a day of &lt;a href="http://www.blogger.com/365%20Days%20of%20Astronomy"&gt;365 Days of Astronomy&lt;/a&gt; project. It is a worldwide project which consists in publishing a podcast (astronomy related) in every single day of 2009. The calendar was almost full but the organization could manage to get me a day. My podcast will be transmitted in &lt;a href="http://365daysofastronomy.org/calendar/"&gt;July 30&lt;/a&gt;. The title is "A Tour through the Lives of the Stars" and I'll talk about stellar evolution. A brief description of the podcast is available in the calendar if you click on the podcast's title.

É claramente visível que, com o avanço das semanas, o seu disco aumenta e a sua fase diminui. Todos os detalhes relevantes estão já incluídos na imagem (clicar para ver em tamanho real!). No entanto, a temporada ainda não acabou e vou ver se consigo acrescentar mais alguns Vénus até este atingir a sua conjunção inferior no dia 27 de Março. Todos os Vénus foram fotografados com SVP 8"+SPC900+ barlow Orion ShortyPlus 2x APO.&lt;br /&gt;----------------------------------------------------------------------------------&lt;br /&gt;With another season of Venus near the end and as I already have a pretty number of photos I made this composition which illustrates the evolution of Venus in the previous weeks. We can see that its disk is increasing in diameter, but its getting narrower with a  phase that is very eye-catching. The relevant details are on the photo (click on it for full size!). However, the season isn't over yet and I will try to add a couple of Venus until March 27, when Venus reaches inferior conjunction. All captured with SVP 8"+SPC900+ barlow Orion ShortyPlus 2x APO.&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-1967476770203499018?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/1967476770203499018/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=1967476770203499018' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1967476770203499018'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1967476770203499018'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/03/venus-evolution.html' title='Venus Evolution'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_DGxhJBZPUVs/Sa0fbRQtbNI/AAAAAAAAAOI/nCqWsRVpeGk/s72-c/VenusEvolution.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-5853917283537853329</id><published>2009-02-28T19:41:00.003Z</published><updated>2009-02-28T19:55:04.442Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Saturno/Saturn'/><title type='text'>Saturno - 23/02/09</title><content type='html'>&lt;a href="http://3.bp.blogspot.com/_DGxhJBZPUVs/SamUHVK6uiI/AAAAAAAAAOA/ymHXKrGVzYQ/s1600-h/Saturn_20090223_0244_CS3.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5307936489495771682" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 278px; TEXT-ALIGN: center" alt="" src="http://3.bp.blogspot.com/_DGxhJBZPUVs/SamUHVK6uiI/AAAAAAAAAOA/ymHXKrGVzYQ/s400/Saturn_20090223_0244_CS3.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div align="justify"&gt;Mais um Saturno. O original encontra-se ao centro com Titã, a sua maior lua, à sua direita. À esquerda está o mesmo Saturno, mas resized a 150%. Desta vez o seeing estava pior e não deu para obter uma melhor imagem e no processamento também me parece bastante escuro. Titã também aparece aqui azulada, mas deveria ser vermelha. Possivelmente será demasiado ténue para a SPC e por isso pode ter havido qualquer problema na detecção das cores. Vou tentar mais vezes, e espero que as condições estejam mais favoráveis.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;Another Saturn. At center, the original with Titan at right and the same Saturn but resized 150% at left. This time, the seeing was worse than the last time and the photo is a little dark. Titan is red, but it came out blue. It may be due to the low brightness of Titan to the SPC.

A SEB (South Equatorial Belt) e EZ (Equatorial Zone) são bem visíveis bem como a NEB (North Equatorial Belt). Os anéis estão quase em linha com a órbita da Terra impossibilitando o vislumbrar da Divisão de Cassini, mas a sombra dos anéis no disco de Saturno é facilmente visível nesta imagem. Note a quantidade de cores presente nesta imagem, gosto bastante das cores deste Saturno. O stacksize é de apenas uns 120 frames de um total de cerca de 1200; para a próxima tenho que aumentar o número de frames capturados para ter um stacksize maior de modo a ter menos ruído na imagem e para aumentar o SNR (Signal to Noise Ratio). O seeing estava razoável, mas espero encontrar noites mais estáveis. Processado no Registax V4 e CS3. Com SkyView Pro 8" EQ+SPC900+UV-IR block+Orion ShortyPlus barlow APO 2x, capturado às 1h04 UT do dia 14 de Fevereiro.&lt;/div&gt;&lt;div align="justify"&gt;---------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This is my first Saturn of 2009(click on the photo for full size); at right the original and at left the same photo resized 150%. SEB (South Equatorial Belt) and EZ (Equatorial Zone) are well visible as well as NEB (North Equatorial Belt). The rings are almost edge on, so the Cassini Division doesn't show up, but the shadow of the rings casted on Saturn's disk is easy to see. Notice all the colour data, I really enjoy the colours on this Saturn. The stacksize is about 120 frame of 1200; next time I have to capture more frames to increase SNR (Signal to Noise Ratio). The seeing was fair but I hope that more stable nights will come. Processed in Registax V4 and CS3. With SkyView Pro 8" EQ+SPC900+UV-IR block+Orion ShortyPlus barlow APO 2x, captured at 1h04 UT on February 14.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-1475688196293296910?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/1475688196293296910/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=1475688196293296910' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1475688196293296910'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1475688196293296910'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/02/1-saturno-de-2009.html' title='1º Saturno de 2009'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://4.bp.blogspot.com/_DGxhJBZPUVs/SZ7Fe6jMoGI/AAAAAAAAANo/VlQ3RUsWp0k/s72-c/Saturn_20090214_0104CS3.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-6881016955013210752</id><published>2009-02-17T23:34:00.004Z</published><updated>2009-02-17T23:54:17.751Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vénus/Venus'/><title type='text'>Vénus - 11/02/09</title><content type='html'>&lt;div align="justify"&gt;&lt;a href="http://3.bp.blogspot.com/_DGxhJBZPUVs/SZtKv_dK4AI/AAAAAAAAANg/BYodvWzVpNM/s1600-h/Venus_20090211_1805CS3.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5303915174506979330" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 300px; TEXT-ALIGN: center" alt="" src="http://3.bp.blogspot.com/_DGxhJBZPUVs/SZtKv_dK4AI/AAAAAAAAANg/BYodvWzVpNM/s400/Venus_20090211_1805CS3.jpg" border="0" /&gt;&lt;/a&gt; Mais um Vénus.

Fotografar DSOs (Deep Space Objects) não tem nada a ver com fotografia planetária/lunar. O objecto eleito foi, como não poderia deixar de ser, a Nebulosa de Orion (M42). A montagem não estava em estação por isso o seguimento foi uma treta, e por isso usei exposições de 2,8s, o que é muitíssimo pouco. Ou era isso ou era voltar para casa de mãos a abanar. Tenho de ver se consigo pôr a montagem em estação mas para já não está a correr lá muito bem. Foto tirada no dia 11 de Fevereiro pelas 22h UT com SVP 8" e DSI. Stacking com Deep Sky Stacker (DSS) e ajustes no CS3 para puxar pela nebulosidade.&lt;/div&gt;&lt;div align="justify"&gt;---------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;Here is my first attempt with my DSI. Imaging DSOs revelead completely different of imaging planets and the moon.  The object chosen was the Orion Nebula (M42). The mount wasn't polar aligned so, there was no good tracking and because of that I could only managed exposure time of about 2.8s (I know, that is almost nothing). I'll try again to polar align the mount. Taken on February 11 at 22h UT with SVP 8" and DSI. Stacked with Deep Sky Stacker (DSS) and adjustments in CS3 to pull out more nebulosity.&lt;br /&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-7666250994091093542?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/7666250994091093542/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=7666250994091093542' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/7666250994091093542'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/7666250994091093542'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/02/1-dso.html' title='1º DSO'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://4.bp.blogspot.com/_DGxhJBZPUVs/SZi2NG21VdI/AAAAAAAAANY/9gOthxulOz0/s72-c/M42_CS3.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-4306411649342759031</id><published>2009-02-14T16:14:00.008Z</published><updated>2009-02-17T23:54:41.079Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vénus/Venus'/><title type='text'>Vénus</title><content type='html'>&lt;a href="http://1.bp.blogspot.com/_DGxhJBZPUVs/SZbubarvzvI/AAAAAAAAANQ/IekUTuCVljI/s1600-h/VenusCS3_20090206_1837jpg.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5302687766062026482" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 384px; CURSOR: hand; HEIGHT: 260px; TEXT-ALIGN: center" alt="" src="http://1.bp.blogspot.com/_DGxhJBZPUVs/SZbubarvzvI/AAAAAAAAANQ/IekUTuCVljI/s400/VenusCS3_20090206_1837jpg.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;p&gt;Mais um Vénus fotografado no dia 6 de Fevereiro às 18h37 UT.

A brilhar intensamente a sudoeste, é difícil passar despercebido. Lá apontei o SkyView Pro 8" e espreitei pela ocular. Lá estava ele, com a sua fase notória e brilhante. Comparativamente à &lt;a href="http://astro-andregoncalves.blogspot.com/2009/01/venus-dichotomy.html"&gt;última vez que o tinha visto&lt;/a&gt; estava consideravelmente maior e com o seu disco menos iluminado e uma fase mais pronunciada. Feitas as contas, cresceu 6" e o seu disco está menos 10% iluminado. Lá usei de novo a ortoscópica com a barlow e...WOW! O único "problema" era o seeing, que parecia não estar tão bom (se bem que bom seeing, anda a escassear por estas bandas). Mas como não sou invejoso, lá meti a SPC900 na barlow para tirar uma foto para partilhar convosco! O resultado está aqui! Um bonito crescente 40% iluminado e com cerca de 31". Tirada em 02/02/09, às 18h09 UT.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;Shinning at magnitude -4.6 in the southwest, Venus isn't hard to notice. I pointed my SkyView Pro 8" and took a look at the eyepiece. There was Venus, bright and its phase was notorious. From &lt;a href="http://astro-andregoncalves.blogspot.com/2009/01/venus-dichotomy.html"&gt;the last time I saw it&lt;/a&gt;, Venus got bigger (it grew 6")and with its disk less illuminated (less 10%). With my ortho and barlow the view was amazing! The only "problem" was the poor seeing. As I am a nice person, I put my SPC900 in the barlow e took this photo to show you!

Vallis Alpes tem um comprimento de 190km e uma largura máxima de 10km. Os Montes Alpes são uma cordilheira situada na parte Norte da Lua e forma a fronteira nordeste do Mare Imbrium. Uma cratera interessante é Cassini. A sua superfície contém várias crateras, dentro dela própria! As duas mais "vistosas" são Cassini A e B, sendo A a maior das duas. Mais abaixo à direita encontram-se os Montes Caucasus que são uma prolongação dos Montes Apenninus e os seus picos mais elevados têm cerca de 6km! A cratera Aristoteles (com cerca de 87km de diâmetro) tem dois picos descentrados, no seu interior e forma um bonito par com Eudoxos. Edege é uma outra cratera, mas bem diferente das últimas. Isto porque o seu interior foi preenchido por lava, restando apenas o seu contorno para contar a história. Reparem nas sombras projectadas pelos picos montanhosos. Esta é uma área que engloba uma grande diversidade de formações.&lt;br /&gt;----------------------------------------------------------------------------------Click on the photo for viewing in fullsize) . On the same day as the previous image, only after a couple of minutes, I pointed the scope just some degrees to the North, at the Vallis Alpes and Montes Alpes region. Vallis Alpes is a lenght of about 190km and a maximum of 10km wide. Montes Alpes forms the northeastern border of the Mare Imbrium. An interesting feature is the Cassini crater, with two remarkable craters inside its rim (Cassini A (the largest) and B). Below we find Montes Caucausus with peaks as height as 6km! It forms a continuation of the Montes Apenninus range to the southwest. Above at right is located Aristoteles and Eudoxos. Aristoteles has two peaks offcenter and Eudoxos has several ones at its center. Edege is a crater which was filled with lava and only its rim remains visible. This area really has a lot of different, remarkable features!&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-5196977256059401967?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/5196977256059401967/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=5196977256059401967' title='2 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/5196977256059401967'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/5196977256059401967'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/02/montanhas-vales-e-diferentes-crateras.html' title='Montanhas, vales e diferentes crateras'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><thr:total>2</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-4752780571656410159</id><published>2009-02-05T02:07:00.014Z</published><updated>2009-02-06T01:30:45.276Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Lua/Moon'/><title type='text'>Montanhas, crateras e...instrumentos de exploração</title><content type='html'>&lt;p align="center"&gt;&lt;a href="http://www.clipartof.com/images/free_hosting/large/0180-0902-0422-2034_mapenninusarea.gif"&gt;&lt;img src="http://www.clipartof.com/images/free_hosting/medium/0180-0902-0422-1254_mapenninusarea.gif" border="0" /&gt;&lt;/a&gt;&lt;/p&gt;&lt;div align="justify"&gt;&lt;br /&gt;Aqui fica uma foto da região dos Montes Apenninus, e fiz um GIF para legendar as partes mais relevantes (clicar na imagem para resolução original). Tirei esta foto com o meu SkyView Pro 8"+barlow APO 2x+ SPC900+UV-IR block, no dia 2 de Fevereiro. A zona dos Montes Apenninus está situada na zona Norte da Lua, a sudeste do grande Mare Imbrium. É, de facto, uma cordilheira formada pelos Mons Wolff , Mons Ampère, Mons Huygens, Mons Bradley, Mons Hadley Delta e Mons Hadley. É um remanescente do impacto que criou Imbrium e pensa-se que se formou pelo levantamento criado pelo impacto, que também escavou uma grande cratera que depois foi inundada por lava, formando o Mare imbrium e preenchendo esse "buraco", apenas sobrando parte dos seus contornos, entre os quais esta cadeia montanhosa. A zona marcada com um B, foi onde a missão Apollo 15 começou, e a letra A assinala o local onde se encontra a módulo lunar utilizado nessa mesma missão. Esta foi a quarta missão tripulada e a primeira a usar um "jipe lunar". A tripulação era composta por David Scott, Alfred Worden e James Irwin e o lançamento deu-se a 26 de julho de 1971. Nas imediações do local A (apelidado de Palus Putredinus) foi também o local em que a soviética Luna 2 se depenhou.&lt;br /&gt;&lt;/div&gt;&lt;div align="justify"&gt;---------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This photo shows the Montes Apenninus area (click on the picture to see the GIF in full size), taken with my SkyView pro 8"+barlow APO 2x+ SPC900+UV-IR block, on February 2nd. It is located on the northern part of the Moon in the southeastern border of the large Mare Imbrium. In fact, it is a mountain range which contains the Mons Wolff , Mons Ampère, Mons Huygens, Mons Bradley, Mons Hadley Delta and Mons Hadley. Apennine Mountains are the remnant of the rim of the Imbrium impact basin and is thought to be made of the uplift of the terrain surrounding the excavated hole. The zone marked with a B, is the location of the Apollo 15 mission and the letter A indicates the place where the lunar module was left by the astronauts David Scott, Alfred Worden and James Irwin in July, 1971. It was the fourth mission to land on the Moon and the first of the "J missions", using a Lunar Rover. On the suburbs of A (Palus Putredinus) is also where the Luna 2 crashed.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-4752780571656410159?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/4752780571656410159/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=4752780571656410159' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/4752780571656410159'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/4752780571656410159'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/02/montanhas-crateras-einstrumentos-de.html' title='Montanhas, crateras e...instrumentos de exploração'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-6639265205655375201</id><published>2009-02-02T15:27:00.011Z</published><updated>2009-02-02T16:19:43.266Z</updated><title type='text'>XMM-Newton reanimado por antena de 34 metros!</title><content type='html'>&lt;div align="justify"&gt;No dia 18 de Outubro do passado ano, o contacto com a XMM-Newton não foi bem sucedido. Após ter comunicado normalmente com uma estação no Chile. Depois da nave deixar de ser contactável a partir do Chile, o seu sinal rádio era esperado por uma estação em Villafranca, Espanha, uma hora depois. No entanto, o contacto rádio não foi reestabelicido como previsto.&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;É um acontecimento relativamente comum com satélites, pois esta falha pode dever-se a um erro num comando, ou um raio cósmico bateu num chip de computador sendo necessário reiniciar a nave. No entanto, verificou-se que não era este o caso. Estaria a nave avariada e a rodar descontroladamente? Teria sido destruída por algum lixo em órbita?&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;3 dias depois, a &lt;em&gt;deep space antenna&lt;/em&gt; de 35 metros da ESA, na Austrália, capturou um fraco sinal da XMM-Newton. A análise do sinal sugeriu uma falha no radio-transmissor (on-board Radio Frequency (RF) switch ). Uma outra antena da 34 metros da NASA em Goldstone, foi usada para enviar um sinal para reiniciar o RF.&lt;/div&gt;&lt;div align="justify"&gt;"XMM-Newton agora está segura e totalmente sob controlo", disse Dietmar Heger, XMM-Newton Deputy Spacecraft Operations Manager no ESOC.&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;Lançada em Dezembro de 1999, a XMM-Newton é um observatório espacial de raios X.&lt;/div&gt;&lt;div align="justify"&gt;--------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;On October 18, after communicate with a tracking station in Chile, the radio signal was expected to be caught in another tracking station in Villafranca, Spain. However, no signal was heard.&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;Its relatively common with satellites; a loss of signal can be due to a mis-typed command or a cosmic ray hit on a computer chip requiring the spacecraft to be rebooted. But it wasn't the case. The fear that XMM-Newton had broken up scared X-ray astronomers.&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;3 days later, the ESA's &lt;em&gt;deep space antenna &lt;/em&gt;with&lt;em&gt; &lt;/em&gt;35 meters, catured a faint signal from the spacecraft. Analysis of the signal suggested a failure in the on-board Radio Frequency (RF) switch. The 34 meter NASA antenna at Goldstone sent a signal to reset the switch.&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;div align="justify"&gt;“XMM-Newton is now safe and fully under control,” said Dietmar Heger, XMM-Newton Deputy Spacecraft Operations Manager at ESOC. &lt;/div&gt;&lt;div align="justify"&gt;Launched on Decermber 1999, the XMM-Newton is a X-ray space observatory. &lt;/div&gt;&lt;div align="justify"&gt;&lt;br /&gt;&lt;/div&gt;&lt;div align="justify"&gt;Fonte: &lt;a href="http://www.esa.int/esaSC/SEM268RTKMF_index_0.html"&gt;http://www.esa.int/esaSC/SEM268RTKMF_index_0.html&lt;/a&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-6639265205655375201?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/6639265205655375201/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=6639265205655375201' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/6639265205655375201'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/6639265205655375201'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/02/xmm-newton-reanimado-por-antena-de-34.html' title='XMM-Newton reanimado por antena de 34 metros!'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-4303778262012271171</id><published>2009-01-17T12:36:00.005Z</published><updated>2009-02-17T23:55:09.634Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Vénus/Venus'/><title type='text'>Venus Dichotomy</title><content type='html'>&lt;a href="http://2.bp.blogspot.com/_DGxhJBZPUVs/SXHR9VDt6SI/AAAAAAAAAL0/NLdmvpbGvvw/s1600-h/Venus_20090116_1753_comp.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5292241888692005154" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 296px; TEXT-ALIGN: center" alt="" src="http://2.bp.blogspot.com/_DGxhJBZPUVs/SXHR9VDt6SI/AAAAAAAAAL0/NLdmvpbGvvw/s400/Venus_20090116_1753_comp.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div align="justify"&gt;Depois de ter fotografado Vénus à cerca de um mês atrás, aqui fica o meu segundo Vénus. As nuvens estavam a ameaçar, e a cobrir o horizonte SW e W, deixando apenas visível um pouco de céu aqui e ali. No entanto, como um bom astrónomo amador que se preze, lá fui em montar o meu colector de fotões. Cerca de 5 minutos depois, o telescópio já tinha condensação, mas o céu estava mais limpo. Vénus parecia uma bola de fogo no céu ao crepúsculo. Lá apontei para Vénus, dei uma olhadela pela ocular, onde se via o seu disco meio iluminado, o seeing apesar de não ter estado particularmente bom, estava muito melhor que da última vez e permitiu-me ver Vénus com a minha ortoscópica e barlow a 333x. Desta vez, não usei filtro UV-IR block na SPC para tentar obter algum detalhe das nuvens venusianas. Ajustei também melhor os settings da webcam de modo a não obter o planeta sobreexposto como da última vez, retocar a focagem e começar a captura do avi de 3 minutos e meio. O resultado final foi a imagem acima (à esquerda, a imagem original; à direita, a mesma imagem resized 150%), com Vénus quase 50% iluminado (dicotomia), no entanto não obtive nenhum detalhe das núvens, o que não me surpreendeu visto que é muito difícil, e que só com filtros IR pass e UV pass é que se consegue obter bons resultados, pois as nuvens venusianas mostram-se melhor no UV. Com SkyView Pro 8"+SPC+barlow 2x APO, no dia 16 de Janeiro, às 17h53 UT.&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;This is my second effort to image Venus. The clouds threatned to cover the sky, but as a good amateur astronomer, I set up my photons collector. Venus was shinning as a fireball in the dusk. Through the eyepiece, I could see Venus half illuminated (dichotomy), and even the seeing wasn't great, it was much better than last time, so, I tried my orthoscopic and barlow combo, and I saw Venus at 333x. This time, I didn't use the UV-IR block filter on my SPC to try to capture some cloud detail and I adjusted the settings to not overexpose the 2º planet. The result was the photo shown here (at left, the original image; at right, the same image resized 150%), where we can see the phase of Venus, but no cloud detail, which is not a surprise because it's hard to get these details without a IR pass and UV pass filters, because the clouds are better seen in UV.

A primeira detecção de metano na atmosfera marciana indica que o planeta ainda está vivo, biológica ou geológicamente, de acordo com uma equipa da NASA e cientistas universitários.&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;"O metano é rapidamente destruído na atmosfera marciana por várias maneiras, por isso a nossa descoberta de focos com subtancial libertação de metano no hemisfério norte de Marte em 2003 indica que há algum processo a decorrer que liberta o gás", diz o responsável Michael Mumma do NASA's Goddard Space Flight Center. "A meio do verão no hemisfério norte, o metano é libertado a uma taxa comparável com o do massivo Coal Oil Point em Santa Barbara, Calif".&lt;/div&gt;&lt;br /&gt;&lt;img id="BLOGGER_PHOTO_ID_5291887485421277730" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 400px; CURSOR: hand; HEIGHT: 233px; TEXT-ALIGN: center" alt="" src="http://2.bp.blogspot.com/_DGxhJBZPUVs/SXCPoV_e0iI/AAAAAAAAALk/PRbz-HpUChY/s400/Sem+t%C3%ADtulo.jpg" border="0" /&gt;&lt;br /&gt;&lt;div align="justify"&gt;Muito do metano na Terra tem origem nos organismos vivos ao obter os seus nutrientes. No entanto, ele pode também ser produzido por processos geológicos, como a oxidação do ferro. "Não temos informação suficiente para dizer se a origem do metano é biológica ou geológica (ou ambas)", diz Mumma. "Mas diz-nos que o planeta ainda está vivo, pelo menos geológicamente".&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;Missões futuras, como a Mars Science Laboratory da NASA, poderão descobrir a origem do metano marciano. Uma maneira de saber se a vida é a fonte de metano é medindo as percentagens de isótopos. Os isótopos são versões mais pesadas de um elemento. Como a vida prefere usar isótopos leves, se o metano tiver menos deutério (isótopo do hidrogénio) que a água libertada com ele, em Marte, é um sinal que é a vida que está a produzir o metano.&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;Seja qual for a fonte de metano que pesquisas futuras revelarão - biológica ou geológica - uma coisa é certa: afinal de contas, Marte não está tão morto quanto isso.&lt;/div&gt;&lt;div align="justify"&gt; &lt;/div&gt;&lt;div align="justify"&gt;&lt;em&gt;Fonte:&lt;a href="http://science.nasa.gov/headlines/y2009/15jan_marsmethane.htm"&gt;http://science.nasa.gov/headlines/y2009/15jan_marsmethane.htm&lt;/a&gt;&lt;/em&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-8499190376845998140?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/8499190376845998140/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=8499190376845998140' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/8499190376845998140'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/8499190376845998140'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/01/afinal-marte-est-vivo.html' title='Afinal Marte Está Vivo'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_DGxhJBZPUVs/SXCPo3Us7dI/AAAAAAAAALs/00gHymq1kIw/s72-c/Sem+t%C3%ADtulo2.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-950877090608125617</id><published>2009-01-14T19:43:00.004Z</published><updated>2009-01-15T16:06:36.767Z</updated><title type='text'>Rádio-mistério</title><content type='html'>&lt;div align="center"&gt;&lt;a href="http://3.bp.blogspot.com/_DGxhJBZPUVs/SW9czWrMOUI/AAAAAAAAALc/ek9vcsz9Rzw/s1600-h/untitled.jpg"&gt;&lt;span style="font-size:78%;"&gt;&lt;img id="BLOGGER_PHOTO_ID_5291550124513442114" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 226px; CURSOR: hand; HEIGHT: 339px; TEXT-ALIGN: center" alt="" src="http://3.bp.blogspot.com/_DGxhJBZPUVs/SW9czWrMOUI/AAAAAAAAALc/ek9vcsz9Rzw/s400/untitled.jpg" border="0" /&gt;&lt;/span&gt;&lt;/a&gt;&lt;span style="font-size:78%;"&gt; Um misterioso sinal ecoa pelo cosmos, impedindo os astrónomos de observar o calor gerado pelas pimeiras estrelas. Foi esta radiação que o ARCADE descobriu. O ruído é 6 vezes maior do que o esperado e os astrónomos não têm ideia do porquê. &lt;/span&gt;&lt;/div&gt;&lt;span style="font-size:78%;"&gt;&lt;/span&gt;&lt;br /&gt;&lt;div align="center"&gt;&lt;/div&gt;&lt;div align="justify"&gt;Uma equipa liderada por Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md., anunciou na semana passada a descoberta de uma nova radiação de fundo, 6 vezes maior do que o previsto.&lt;br /&gt;&lt;/div&gt;&lt;div align="justify"&gt;A descoberta foi feita pelo ARCADE (Radiometer for Cosmology, Astrophysics, and Diffuse Emission), a bordo de um balão a uma altitude de cerca de 36 500 metros.&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;"Em vez do fraco sinal que esperávamos encontrar, lá estava este ruído 6 vezes maior do que se previa". Análises detalhadas excluiram a hipótese de a origem ter vindo de estrelas primordiais ou de fontes rádio conhecidas. A fonte desta radiação de fundo permanece, por isso, em mistério.&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;"Isto é o que torna a ciência tão excitante", diz Michael Seiffert, um membro da equipa no NASA's Jet Propulsion Laboratory em Pasadena, Calif. "Traças um caminho para medir algo - neste caso, o calor emitido pelas primeiras estrelas - mas dás de caras com outra coisa completamente diferente e inexplicável".&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;O ARCADE é o primeiro instrumento suficientemente preciso para detectar esta radiação misteriosa. Para aumentar a sua sensibilidade dos seus receptores rádio, estes foram imersos em mais de 2 270 litros de hélio líquido a 2,7 Kelvin ( -270,3 ºC).&lt;br /&gt;&lt;br /&gt;Este é a mesma temperatura que a radiação cósmica de fundo (CMB), descoberta em 1965. " Se o ARCADE está à mesma temperatura que a CMB, então o calor do instrumento não contamina o sinal", explica Kogut.&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-950877090608125617?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/950877090608125617/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=950877090608125617' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/950877090608125617'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/950877090608125617'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/01/rdio-mistrio.html' title='Rádio-mistério'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/SW9czWrMOUI/AAAAAAAAALc/ek9vcsz9Rzw/s72-c/untitled.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-4117443876054537769</id><published>2009-01-10T20:41:00.003Z</published><updated>2009-01-10T20:54:57.044Z</updated><title type='text'>Maior Lua Cheia do Ano</title><content type='html'>&lt;div align="justify"&gt;Este final de semana a Lua atingiu a fase de Lua Cheia e, simultâneamente, encontra-se no perigeu (momento em que está mais próxima da Terra, que atinge uma vez por mês (podendo atingir duas vezes)).

Os astrónomos têm vindo a descobrir que as galáxias supermassivas alojam buracos negros nos seus centros, e ainda outra peculiaridade: qualquer que seja a massa do buraco negro, o bojo da sua galáxia é constituído por estrelas velhas e contém sempre cerca de 700 vezes essa massa. Agora a questão que surge é: quem nasceu primeiro, o buraco negro ou a galáxia?&lt;br /&gt;&lt;/p&gt;&lt;p align="justify"&gt;Quarta-feira, novos resultados foram anunciados sugerindo que foram os buracos negros que primeiro se formaram. Uma equipa internacional liderada por Chris Carilli (National Radio Astronomy Observatory) usando vários radiotelescópios em vários países, observaram 4 quasares distantes (galáxias com forte actividade no seu núcleo brilhante, provocada pelo seu buraco negro). Devido à sua grande distância entre nós, a luz que nos chega foi a que partiu desses quasares apenas mil milhões de anos (ou menos) depois do Big Bang!&lt;/p&gt;&lt;p align="justify"&gt;Os resultados obtidos revelaram que o bojo era apenas 30 vezes mais massivo que o buraco negro. "Em todos os quatro casos, as massas dos buracos negros eram 20 a 30 vezes maiores do que o previsto com base na relação observada no Universo nas redondezas", diz Carilli. "A conclusão mais simples é que primeiro surgiram os buracos negros, e de alguma forma cresceram galáxias à sua volta".&lt;/p&gt;&lt;p align="justify"&gt;No entanto, Carilli aponta que estes resultados necessitam de ser confirmados com observações futuras, inclusivé melhores estudos com grandes radiotelescópios actualmente em construção, nomeadamente&lt;span style="color:#cccccc;"&gt; &lt;/span&gt;&lt;span style="color:#ffffff;"&gt;o Expanded Very Large Array (EVLA) e o Atacama Large Millimeter/submillimeter Array (ALMA).&lt;/span&gt;&lt;/p&gt;&lt;p align="justify"&gt;&lt;span style="color:#000000;"&gt;&lt;span style="color:#ffffff;"&gt;Fonte:&lt;/span&gt; &lt;a href="http://www.nrao.edu/pr/2009/bhbulge/j1148.slide.jpg"&gt;http://www.nrao.edu/pr/2009/bhbulge/j1148.slide.jpg&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-1146254691283274852?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/1146254691283274852/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=1146254691283274852' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1146254691283274852'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/1146254691283274852'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2009/01/buracos-negros-e-galxias-quem-nasceu.html' title='Buracos Negros e Galáxias: Quem Nasceu Primeiro?'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-7973127073181264426</id><published>2009-01-03T19:50:00.002Z</published><updated>2009-01-03T19:56:55.704Z</updated><title type='text'>AIA 2009</title><content type='html'>&lt;div align="justify"&gt;2009 é o Ano Internacional da Astronomia, 400 anos depois de Galileu Galilei apontar o seu telescópio para o firmamento.

O seu brilho intenso dificultou um pouco a captura, mas depois de alguma paciência e retoques na focagem Vénus lá se fez ver, com a sua fase de 63% bem notória e o seu disco de 19,2". Ainda estava o céu azul apesar de o Sol já se ter posto para capturar Vénus com a maior altura possível em relação ao horizonte, mas mesmo assim o seeing estava fraco.

Its bright made the capture a little tricky, but with some patient and accurate focus, Venus showed up on my laptop screen with its disk of 19,2" and 63% illuminated. At the time the sky still was light blue because I wanted to catch Venus high in the sky but the seeing wasn't good.

No entanto, este ano a lua cheia (que é a maior e a mais brilhante do ano!) vai "estragar" o espetáculo pois o seu brilho não permitirá ver os meteoros mais ténues o que fará diminuir o número habitual de 100 meteoros por hora para cerca de 20 meteoros por hora.&lt;br /&gt;&lt;br /&gt;Chamam-se Geminidas pois o radiante (local no céu de onde parecem vir os meteoros) situa-se na constelação de Gémeos. Este chuva acontece anualmente quando a órbita da Terra cruza o rasto de poeiras deixado pelo cometa 3200 Phaethon que já se encontra extinto.&lt;br /&gt;----------------------------------------------------------------------------------&lt;br /&gt;The Gemini meteor shower peaks on December 13th and 14th, but this year the show will be spoiled by the almost full moon which is the biggest full moon of the year. In a dark sky it usually achieves rates of 100 meteors per hour, but this year it should be about 20 meteors per hour because of the glare of the moon.&lt;br /&gt;&lt;br /&gt;They are called Geminids because meteors seem to come from the constelation of Gemini.

Eram 01:53 UT+1 (hora local) com a Lua já a caminhar em direcção ao horizonte, por isso decidi ir até à praia tentar apanhar alguma estrela cadente. Enquanto o pôr-da-Lua não acontecia resolvi tirar umas fotos ao céu, mas desta vez com uma pitada de areia e mar. No lado direito vê-se a Lua quase a pôr-se, Júpiter quase no centro, a constelação de Sagitário e, com um olhar mais atento é possível ver um vislumbre da Via Láctea. Aqueles dois focos de luz eram de uma discoteca nas redondezas e, na minha opinião, até enriqueceram a foto. Como eu também queria aparecer na linda cena, coloquei a Sony Alpha 100 num tripé, com temporizador de 10 segundos para ter tempo de ir para frente da câmara e contemplar toda a cena. Capturada com 20 segundos de exposição a ISO1600 (o CCD desta DSLR apresenta pouco ruído, mesmo com o ISO elevado!).&lt;/div&gt;&lt;div align="justify"&gt;----------------------------------------------------------------------------------&lt;/div&gt;&lt;div align="justify"&gt;(Click for viewing in full size)&lt;br /&gt;On 12th August, I was on holidays in Manta Rota-Algarve, Portugal. At 01:53 UT+1 the Moon was setting, so I have decided to go to the beach to see some perseids. The view was fantastic! The moonset, Júpiter, Sagittarius and the milkyway. I have enjoyed the scene so much that I wanted to take part of it. I set the timer of Sony Alpha 100 to 10s on a tripod and went to the front of the camera.

It seemed a scenario of a horror movie.

A juntar-se ao espetáculo na esfera celeste, juntaram-se algumas árvores, luzes de iluminação pública bem como a vedação, dando à fotografia mais beleza.

Só tive tempo de pegar na máquina, ir para a varanda, montá-la no tripé fotográfico apontar mais ou menos para a zona...e quando dou conta e olho para o céu já vejo o flare já a meio...centro-o no LCD à pressa e disparo. Resultado: apanhei cerca de metade do flare. Isto é a prova de que com mais planeamento saíria tudo bem. Fica para a próxima. Na imagem é visível a constelação da Virgem, a sua estrela mais brilhante Spica e a dupla Porrima, entre outras, bem como uma pequena parte do Leão.&lt;br /&gt;Captura com Fuji S5600, 15s exposição a f/3,2, ISO 200.&lt;br /&gt;(A imagem é mais agradável se vista em ecrã inteiro.

I only had time to grab the camera, mount it on a tripood and shoot. The result was a "half-flare". Previous planning is essencial in this kind of photos. Next time will came out better. Looking at the picture is visible the constelation Virgo and a little of Leo.&lt;br /&gt;Taken with Fuji S5600, 15s exposure at f/3,2, ISO 200.&lt;br /&gt;(The picture is recommended to view at full screen) &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4674783424921739617-788629598490241482?l=astro-andregoncalves.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://astro-andregoncalves.blogspot.com/feeds/788629598490241482/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=4674783424921739617&amp;postID=788629598490241482' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/788629598490241482'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/4674783424921739617/posts/default/788629598490241482'/><link rel='alternate' type='text/html' href='http://astro-andregoncalves.blogspot.com/2008/06/iridium57-na-virgem.html' title='Iridium57 na Virgem'/><author><name>André Gonçalves</name><uri>http://www.blogger.com/profile/07960786743044869242</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='http://3.bp.blogspot.com/_DGxhJBZPUVs/Sq7gjjAoMlI/AAAAAAAAAVU/uyYoJot-vtM/S220/DSC01808.jpg'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_DGxhJBZPUVs/SFD6nWt_dBI/AAAAAAAAAFQ/ZHUQx8cub2I/s72-c/Iridium57_lines.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-4674783424921739617.post-6782438456095774662</id><published>2008-05-26T20:57:00.003+01:00</published><updated>2008-12-11T03:39:28.756Z</updated><category scheme='http://www.blogger.com/atom/ns#' term='Outros/Miscellaneous'/><title type='text'>LRO - Send your name to the moon</title><content type='html'>&lt;a href="http://2.bp.blogspot.com/_DGxhJBZPUVs/SDscwqYCznI/AAAAAAAAAFI/g89eX4pPE5g/s1600-h/Sem+t%C3%ADtulo.jpg"&gt;&lt;img id="BLOGGER_PHOTO_ID_5204785416691175026" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://2.bp.blogspot.com/_DGxhJBZPUVs/SDscwqYCznI/AAAAAAAAAFI/g89eX4pPE5g/s400/Sem+t%C3%ADtulo.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;Quem nunca desejou ir numa sonda espacial?

Aqui fica uma imagem do estado do Sol no dia 11 de Novembro de 2006 que apresentava uma mancha solar. O equipamento usado foi um Solarscope e uma máquina fotográfica digital Benq DC2300. No Solarcope o Sol aparece esbranquiçado e as manchas solares negras, no entanto para dar uma cor mais "habitual" e apelativa  mexi nas "curves" no CS3 para dar um tom alaranjado, bem como outros settings para realçar a mancha solar.
