Galaxy Clusters

Galaxy clusters are groups of galaxies gravitationally interacting with each other. Our own galaxy, The Milky Way Galaxy, is a member of the Local Group galaxy cluster. This page contains images of multiple galaxies and galaxy clusters. It also contains images of interacting galaxies, which themselves are not galaxy clusters, but are certainly part of a larger cluster. Most large galaxies, including the Milky Way, contain many satellite galaxies gravitationally bound to it. It is thought that larger galaxies become even larger by absorbing smaller galaxies.
