About this Image
This crop on the central part of the Pelican Nebula (IC 5070) is showing the bright and complex shock front featuring a similar shape as the famous Cygnus Wall in the larger North America Nebula.
Highly energised shock fronts give a high contrast to the adjacent areas, filled with complex dark gas and dust lanes.
