NGC 6888

An emission nebula in the Constellation Cygnus, the Crescent Nebula (NGC 6888) is formed from the faster stellar wind created by Wolf-Rayet star WR136 colliding with the slower wind created by this same star when it became a red giant. The result of this collision is a shell and two shock waves, one moving outward and one moving inward. This bright star can be seen in the center of the nebula. It is burning up its fuel at a tremendous rate and will likely end its life as a supernova.
