IC 5146

IC 5146, also known as the Cocoon Nebula, is an emission and reflection nebula located in the constellation Cygnus. It is part of a star-forming region and is approximately 2,600 light-years away from Earth. The nebula is notable for its distinctive shape, resembling a cocoon, which is formed by a dense cloud of gas and dust. Within this cloud, new stars are being born, which heat the surrounding material and cause it to emit light.
