Cresent Nebula

The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away. It was discovered by Friedrich Wilhelm Herschel in 1792. It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000 to 400,000 years...

Pelican Nebula

This is a portion of the Pelican Nebula, in the constellation of Cygnus, the Swan. The “mountains” in this image are formed by an area of denser gas and dust that is slowly being eroded away by the ultraviolet radiation from nearby young, hot stars, forming what is known as an ionization front. By using special filters to isolate the light from individual chemical elements, and assigning these elements to different colors, subtle variations in the energy levels within the cloud can be brought into stark detail. Light from oxygen atoms is shown as orange, and represents the highest energy.¬†Green represents...
