The Crescent Nebula (also known as NGC 6888, Caldwell 27) is located in the constellation Cygnus. It is formed by the fast stellar wind from a Wolf-Rayet star 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 ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward.
Size: 25 light-years across (A light year is roughly 6 trillion miles)
