The nebula NGC 6888 is a shell of gas that is being energized by the strong stellar wind from the Wolf-Rayet star WR 136, the bright star at the center of the nebula. It is located in the constellation of Cygnus, the Swan. Wolf-Rayet stars are very hot, massive stars that are blowing off their outer layers.
