The Cocoon Nebula, or IC 5146, is a fantastic nebula 4,000 light-years away in Cygnus. Inside the nebula is a newly developing star cluster. At the same time, the nebula contains bright red emission, blue reflection nebulas, and dark absorption nebulas. The star to the left is believed to have created a hole in the molecular cloud. This same star provides much of the energy for the light emitted by the nebula.
