The Pelican Nebula (also known as IC5070 and IC5067) is a H II region close to Deneb the brightest star in the constellation of Cygnus and divided from its brighter, larger neighbour, the North American Nebula by a molecular cloud filled with dark dust (just visible on the left in this image). The Pelican is of great scientific interest because it is an active mix of star formation and evolving gas clouds. The light from young energetic hot stars is slowly heating this gas causing an ionization front to advance outwards (right hand side of image). Dense filaments of cold gas are still visible and are rich in ionised oxygen (blue central portion of the image). Source - Modified from wikipedia. http://en.wikipedia.org/wiki/Pelican_Nebula
