The Coma Supercluster is a massive group of galaxies located in the northern sky, primarily within the constellation Coma Berenices. It is one of the largest known structures in the universe, containing thousands of galaxies, including the prominent Coma Cluster, which is a rich cluster of galaxies. This supercluster spans over 20 million light-years and is part of the larger Laniakea Supercluster, which includes our own Milky Way Galaxy. The Coma Supercluster plays a significant role in the study of cosmic structure and the distribution of galaxies in the universe.
