The Coma Cluster of galaxies is one of the densest collections of galaxies in the universe. The Hubble Space Telescope's Advanced Camera for Surveys viewed a large portion of the cluster, spanning several million light-years across. This cluster contains thousands of galaxies and lies near the Milky Way's north pole, about 300 million light-years away from Earth. This movie combines the work of ground- and space-based observations. Its first part starts with a ground-based image from Akira Fujii, then transitions to imaging from the Digitized Sky Survey. The zoom ends with a closer look at Hubble's mosaic of the Coma Cluster.
