The Coma Galaxy Cluster
The Coma Galaxy Cluster located in the constellation Come Berenices about 300 million light years away. This cluster is one of the most dense galaxy clusters known, numbering well over a thousand. Almost all of the objects in this image are galaxies and most of these galaxies are elliptical. The two large ones (fuzzy) in the center are supergiant galaxies.
