Description

5000LY distant located in the constellation Cygnus the Crescent Nebula is about 26LY across, a shock wave of ionized material forming the beautiful emission nebula we see today.

250,000 years ago the star WR 136 expelled much of its material in to space as it became a red giant, now a very powerful emitter of radiation and a fast highly charged solar wind from the Wolf-Rayet star is colliding with the shell expelled during the red giant phase creating a bubble of gas which is heated to x-ray emitting temperatures.
