The Eridanus Galaxy Cluster is a group of galaxies located in the constellation Eridanus. It is one of the nearest galaxy clusters to Earth, situated about 60 million light-years away. This cluster contains several notable galaxies, including the giant elliptical galaxy NGC 1407. The Eridanus Galaxy Cluster is part of a larger structure known as the Laniakea Supercluster, which encompasses our own Milky Way Galaxy. The cluster is rich in both galaxies and hot gas, making it an important area for studying galaxy formation and evolution in the universe.
