NGC 6820 an emission nebula in a star forming region about 6,000 light-years away in the constellation of in Vulpecula. It surrounds the relatively young open cluster of stars, NGC 6823. Numerous pillars of dense gas lay on the edges of a cavity eroded by UV radiation from the cluster's hot, young stars. Similar pillars can be seen in CED 214, the Eagle nebula, the Pelican nebula, and IC 1396.
