The disturbed galactic duo NGC 3169 (left) and NGC 3166 (right)
NGC 3169 is a spiral galaxy about 75 million light years away in the constellation Sextans. It has the morphological classification SA(s)a pec, which indicates this is a pure, unbarred spiral galaxy with tightly-wound arms and peculiar features. There is an asymmetrical spiral arm and an extended halo around the galaxy.
NGC 3166 (also known as IRAS 10111 + 0340, MCG 1-26-24, PGC 29814 and UGC 5516) is a barred spiral galaxy that is about 62 million light years from Earth and is located in the constellation Sextans. The first discovery was made by John Frederick William Herschel 19th December 1783
This image from the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile captures the pair of galaxies NGC 3169 and NGC 3166. These adjacent galaxies display some curious features, demonstrating that each member of the duo is close enough to feel the distorting gravitational influence of the other. The gravitational tug of war has warped the spiral shape of one galaxy, NGC 3169, and fragmented the dust lanes in its companion NGC 3166. At the bottom-right of the pair, a third galaxy is portrayed, NGC 3165.

Mixing Galaxies:
What happens when you combine a spiral galaxy with an elliptical galaxy? Although it may sound like a punch-line should follow, NGC 6340 appears to be the result:
http://skycenter.arizona.edu/gallery/Galaxies/NGC6340
Over the years this lenticular galaxy has been studied by astronomers due to its distinctly different populations of stars. Most likely this galaxy was formed by the collision of two and has slowly been evolving into form we see today. IC 1254 to the upper left also seems to be in the midst of collision by virtue of the large (faint) plume associated with it. This image may be the deepest high resolution color image of these galaxies to be published to-date.

Estrela Rigel/ Constelação de Órion
Rigel, uma estrela supergigante azul que pode ser observada na constelação de Órion, sendo a estrela mais brilhante desta constelação. Rigel tem uma magnitude aparente de +0,12 o que significa que ela é relativamente brilhante vista da Terra. A distância da estrela Rigel não é conhecida com tanto vigor, porém estima-se uma distância de 800 anos-luz, mais com uma margem de erro significativa. Esta estrela tem aproximadamente uma massa equivalente a 20 massas solares e é algumas dezenas de milhares de vezes mais brilhante que o Sol. Estas características fazem de Rigel uma estrela gigantesca, sendo classificada como uma "estrela supergigante azul".
Dada a elevado massa desta estrela, provavelmente terá um tempo de vida curto (à escala do tempo de vida das estrelas), terminando numa supernova e posteriormente em um buraco negro. Quanto mais quente e brilhante for uma estrela, mais depressa ela consome hidrogênio e consequentemente chega mais depressa ao fim de sua vida, sendo esse o caso de estrelas supergigantes azuis de massa bastante elevada. Já as estrelas relativamente frias e pouco brilhantes tem uma vida muito mais longa, como é o caso das estrelas anãs vermelhas.
Rigel faz parte de um sistema de 3 estrelas, sendo que outros dois elementos são conhecidos por Rigel B e Rigel C, elementos esses significativamente mais pequenas e menos brilhante que Rigel.

Vertically across the image left is part of the plane of our Milky Way Galaxy. Visible there are vast clouds of bright stars and long filaments of dark dust. Jutting out diagonally from the Milky Way in the image center are dark dust bands known as the Dark River. This river connects to several bright stars on the right that are part of Scorpius' head and claws, and include the bright star Antares. Above and right of Antares is an even brighter planet Jupiter. Numerous red emission nebulas and blue reflection nebulas are visible throughout the image. Scorpius appears prominently in southern skies after sunset during the middle of the year.
Alpha Centauri is a binary star system consisting of Alpha Centauri A and Alpha Centauri B. This wide-field view of the sky around the bright star Alpha Centauri was created from photographic images forming part of the Digitized Sky Survey 2. The star appears so big just because of the scattering of light by the telescope’s optics as well as in the photographic emulsion. Alpha Centauri is the closest star system to the Solar System.

Deneb is the brightest star in the Cygnus constellation and one of the brightest stars in the night sky, with apparent magnitude 1.25.
Deneb's absolute magnitude is −8.73, placing it among the most luminous stars known. Deneb's exact distance from the Earth is a matter of some dispute; figures from 1600 to 3200 light years appear on various online sources. Estimates for Deneb's luminosity range from about 60,000 to 250,000 times the Sun's brightness. If placed at the same distance of Sirius from us, Deneb would be brighter than the full moon.

La galaxia IC1613 es una especie de Isla del Tesoro para los estudiosos de las estrellas masivas. Esta galaxia irregular enana todavía está formando estrellas, y descubrimos nuevas estrellas masivas con cada apuntado del GTC. Estos objetos experimentan altas temperaturas en su juventud y somos capaces de detectarlos con telescopios espaciales en el rango UV, lo que se refleja en los colores azules de la imagen.
IC1613 tiene una reserva de gas hidrógeno neutro, la materia prima de donde se forman las estrellas, y que en la imagen vemos como una nube blanquecina. Las estrellas masivas jóvenes son capaces de ionizar la nube de hidrógeno en la que se formaron, y forman las burbujas rojizas que se ven en toda la imagen y su variante más espectacular en la parte inferior izquierda de la galaxia. IC1613 se ha convertido en foco de atención en los últimos años por su composición química, mucho más parecida a la del Universo primitivo que la de la Vía Láctea.
A través del estudio de las estrellas masivas en IC1613, nos acercaremos un paso más a saber cómo eran las primeras estrellas del Universo.

Rho Ophiuchi Cloud Complex 4/19/2015
This has been a dream target of mine ever since I started getting into Astrophotography. The dust structure and colors of the Rho Ophiuchi Cloud Complex to me is a prime example of the magnificent beauty that can be found in the night sky. At 460 light years away from our solar system this is one of the closest star forming regions to us. Covering an angular area of of 4.5° × 6.5° it takes up a very sizable portion of the night sky; for reference the full moon is on average 0.5° across or half of the size of the tip of your pinky finger at arms length. This image represents 3 hours of exposure time, I plan on many more hours in the future!

NGC 6826
Al nacer una estrella, casi todo lo que la forma es hidrógeno; por reacciones que ocurren en su núcleo, se produce helio y, a partir de éste, carbono. En la imagen, la nebulosa NGC 6826.
In the Heart of the Rosette Nebula
Image Credit & Copyright: Don Goldman
Explanation: In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail. A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. The Rosette Nebula's center measures about 50 light-years across, lies about 4,500 light-years away, and is visible with binoculars towards the constellation of the Unicorn (Monoceros).

Lupus 3 - Constellation du Scorpion
Une nouvelle image évocatrice de l'ESO montre un nuage sombre où de nouvelles étoiles se forment, le long d'un amas d'étoiles brillantes qui ont déjà émergé de leur pépinière stellaire poussiéreuse. La nouvelle image a été prise avec le MPG / ESO de 2,2 mètres télescope de l'Observatoire de La Silla, au Chili et est la meilleure image jamais prise en lumière visible de cette région du ciel.
Ce nuage est connu sous le nom de lupus 3. Il se trouve à environ 600 années-lumière de la Terre dans la constellation du Scorpion. La section représentée ici est d'environ cinq années-lumière.
