Inside the Coma Cluster of Galaxies

Almost every object in this photograph is a galaxy. This is the Coma Cluster of Galaxies, one of the densest known clusters, containing thousands of galaxies. Each galaxy, like our Milky Way, houses billions of stars. Light from the Coma Cluster takes hundreds of millions of years to reach us, and it takes millions of years for light to cross the cluster itself.
