description NGC 6888 Overview
NGC 6888, commonly called the Crescent Nebula, is an emission nebula in the constellation Cygnus. It formed as fast stellar wind from the Wolf-Rayet star WR 136 collided with material expelled during an earlier phase of the star's evolution, producing an expanding shell of energized gas. Its curved filaments and bubble-like structure make it a frequent target for professional study and deep-sky astrophotography.
