The Coma Cluster is a large group of galaxies located about 320 million light-years away from Earth in the constellation Coma Berenices. It contains over 1,000 galaxies, with many being elliptical and spiral types. The cluster is one of the richest known clusters in the universe and is a key area for studying galaxy formation and evolution. This cluster is part of the larger Laniakea Supercluster, which includes our own Milky Way Galaxy. The Coma Cluster is also notable for its high concentration of dark matter, which influences the motion of galaxies within it. Scientists study this cluster to better understand cosmic structures and the behavior of galaxies.
