Description

NGC6888 Crescent Nebula

The Crescent Nebula is an emission nebula about 5000 light-years away and 25 light-years across. It is formed by fast stellar wind from a nearby star energizing slower moving wind previously ejected by the star when it became a red giant about 300,000 years ago. Visually the nebula is a rather faint object which looks like a crescent or Euro-sign in a large telescope, giving it another name: the "Euro Sign Nebula". North is at the top.
