The Coma Cluster is one of the densest known galaxy collections in the universe. It contains thousands of galaxies in a spherical shape more than 20 million light-years in diameter and located at over 300 million light-years from the Sun. Most of the objects in the central portion are elliptical galaxies, which contain populations of old stars. Farther from the centre are several spiral galaxies, where star birth takes place.
