IC5067 is an ionization front within the larger Pelican Nebula (IC 5070)
The Pelican Nebula is slowly being transformed and is divided from the larger North America Nebula by a
molecular cloud filled with dark dust. The Pelican Nebula receives much study because it is a particularly
active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly
transforming the cold gas to hot gas, with the advancing boundary between the two known as an ionization front.
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.
The prominent ridge of emission featured in this dramatic skyscape is cataloged as IC 5067. The ridge spans about 10 light-years following the curve of the cosmic pelican's head and neck. Fantastic, dark shapes inhabiting the image are clouds of cool gas and dust sculpted by the winds and radiation from hot, massive stars. Close-ups of some of the sculpted clouds show clear signs of newly forming stars. The Pelican Nebula, itself is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus. sources:
