COMMENTS: The Pelican Nebula (also known as IC5070 and IC5067) is a large area of emission nebula in the constellation Cygnus (the Swan) close to Deneb. It is divided from its brighter, larger neighbor, the North America Nebula, by a molecular cloud filled with dark dust. This nebula is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain. Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.
