COMMENTS ON THE PHOTO:
IC 5146 consists of an emission nebula and an open cluster located around 4,000 light-years from Earth in the constellation Cygnus. Its shape is reminiscent of a cocoon, hence its common name. It is about 15 light-years across. It lies near the eastern edge of the constellation, close to the Lizard constellation, right in the Milky Way. Like other star-forming regions, it is characterised by bright red hydrogen gas excited by hot young stars and a slightly bluish starlight reflected by dust at the edge of a molecular cloud. The bright star near the centre of this nebula is only a few hundred thousand years old. It is this star that illuminates most of the nebula and brings out the very beautiful shades of red in the nebula.
