The Pelican Nebula<\/b> (also known as IC 5070 and IC 5067<\/b>[1]<\/a><\/sup>) is an H II region<\/a> associated with the North America Nebula<\/a> in the constellation<\/a> Cygnus<\/a>. The gaseous contortions of this emission nebula<\/a> bear a resemblance to a pelican<\/a>, giving rise to its name.[1]<\/a><\/sup> The Pelican Nebula is located nearby first magnitude<\/a> star Deneb<\/a>, and is divided from its more prominent neighbour, the North America Nebula, by a molecular cloud<\/a> filled with dark dust<\/a>.<\/p>\n

The Pelican is much studied because it has a particularly active mix of star formation<\/a> and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization<\/a> front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain, and among these are found two jets emitted from the Herbig\u2013Haro object<\/a> 555.[1]<\/a><\/sup> 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.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
