Description

The Cocoon Nebula, cataloged as IC 5146, is a strikingly beautiful emission nebula and star cluster located about 4,000 light years away in the constellation Cygnus. It is located near the star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M 39.

IC 5146 shines at magnitude 7.2, and has an apparent diameter of 12', which is equivalent to a span of 15 light years.

Inside the Cocoon Nebula is a newly developing cluster of stars. The massive central star, which formed about 100,000 years ago, now provides the energy source for much of the emitted and reflected light from this nebula.
