Back of the Peicans Neck


Sometimes a change of focal length on a object normally associated with another focal length can yield unexpectedly good results. This is a closer look than normal at the prominent ridge of emission featured in neck and back of head area of the Pelican nebula. This area is designated as IC 5067. A delightful swirl of dust lanes, dark clouds of cooler dust that cloak the formation of new stars. At the tip of the center dark tendril twin jets emerge and are one of the signs of a protostar forming that has been cataloged as Herbig-Haro 555.

The Pelican 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.
