NGC 6888 also known as the Crescent Nebula is formed by the fast stellar winds from a Wolf-Rayet star colliding with and energizing the slower moving wind ejected by the same star when it evolved to a red giant 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. Discovered by Friedrich Wilhelm Herschel in 1792
