NGC 6888, also known as the Crescent Nebula, is an emission nebula in
Cygnus. It has an apparent size of 12 x 18 arc minutes and is located at a
distance of about 5,000 light years. The glow comes from the stellar wind from a
Wolf-Rayet star which is colliding and energizing the surrounding gas from
previous ejections.
