About this Image
The Pelican Nebula (IC 5070) in central Cygnus, here shown in narrowband color, is divided from the larger North America Nebula by a molecular cloud filled with dark dust.
Highly energised shock fronts give a high contrast to the adjacent areas, filled with complex dark gas and dust lanes.
