This is the Crescent Nebula, NGC 6888, an emission nebula in the constellation Cygnus. It is about 5000 light-years away from Earth. The nebula is formed by the fast stellar wind from the Wolf-Rayet star WR136 colliding with the slower moving wind ejected by the star when it became a red giant around 250,000 years ago.
