Explora Emitem Radiação, Brilho Vermelho e outros!

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.

The Fox Fur Nebula ~ The region just below and to the right of S Mon, the bright star in the above picture, is nicknamed the Fox Fur Nebula for its color and texture. The blue glow directly surrounding S Mon results from reflection, where neighboring dust reflects light from the bright star. The more diffuse red glow results from emission, where starlight ionizes hydrogen gas. Pink areas are lit by a combination of the two processes. S Mon is part of a young open cluster of stars named NGC…

Trifid Nebula ...beautiful, but can't help but think of the movie 'Day of the Triffids'.

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.

Contando as estrelas

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

The deep beautiful lush purple & pink fused colours of the Orion Nebula...resonate throughout our galaxy...
