See it on NASA's siteAlmost every object in this photograph is a galaxy belonging to the Coma Cluster. This is one of the densest known clusters, containing thousands of galaxies, each with billions of stars. Light from the Coma Cluster takes hundreds of millions of years to reach us, and millions of years to cross the cluster itself.
