Coma Cluster

The Coma Cluster is a large group of thousands of galaxies bound together by gravity, spanning millions of light-years. It's one of the most studied galaxy clusters, showcasing a mix of galaxy types, hot gas, and dark matter. The hot gas emits X-rays, revealing the cluster's enormous mass and structure. By examining the Coma Cluster, scientists learn about galaxy evolution, the distribution of dark matter, and the universe's large-scale structure. Its relatively close proximity makes it an important object for understanding how galaxies and cosmic matter cluster together in the universe.
