NGC 896, uma nebulosa escura composta de gás e poeira, permitindo que a matéria-prima para o processo de formação de estrelas. Depois de tornar-se livre de seu nascimento mortalha, as estrelas mais massivas, azul e quente, emitem radiação causando o brilho vermelho do gás hidrogênio.
NGC 6914 Nebulae is about 6000 ly away, toward Cygnus & the plane of our Galaxy. The view spans nearly 50 ly. UV radiation from the massive/ hot/ young stars of Cygnus OB2 ionize the region's atomic hydrogen gas, producing a characteristic red glow as protons & electrons recombine. Embedded Cygnus OB2 stars also provide the blue starlight reflected by the dusty clouds.
2011 January 20: Andromeda M31. Two European space observatories teamed up to produce this image of the Andromeda Galaxy. The Herschel space telescope focused on rings of star formation in infrared light, shown here in shades of red and orange. The XMM-Newton probe registered the X-ray emissions from exploding stars, shown here in blue. M31 is the largest Galaxy of the Local Group, which consists of: Andromeda Galaxy, Milky Way Galaxy, Triangulum Galaxy, and at least 30 other smaller…
Antares & friends Antares is a supergiant star with a stellar classification of M1.5Iab-b. It has a radius of approximately 883 times that of the Sun; if it were placed in the center of our solar system, its outer surface would lie between the orbits of Mars and Jupiter. via Dark Matter on Facebook http://www.facebook.com/pages/Dark-Matter/113077625507306
