Cocoon nebula


By  Márk Huszáros

The Cocoon Nebula is cataloged as IC5146. This star-forming region is nearly 4000 light years away from our solar system, around 15 ly wide and located in the constellation of Cygnus close to the naked-eye star Pi Cygni. The Cocoon gets its red light from the hydrogen-alpha emmitation and the blue colour comes from reflection on the surface of the dust clouds.
