Pelican Nebula Mosaic

This is a portion of the Pelican Nebula and North America Nebula, in the constellation of Cygnus, the Swan. The “mountains” in this image are formed by an area of denser gas and dust that is slowly being eroded away by the ultraviolet radiation from nearby young, hot stars, forming what is known as an ionization front. This image is a Ha filter exposure colored in red.
