The Coma Cluster
March 17, 2003
The extensively studied Coma cluster, lying near the north galactic pole and nearly 100 megaparsecs (about 326 million light-years) away, contains more than 1000 bright galaxies. A note of interest about this image - it shows the merging of the larger, brighter central cluster and the fainter group of galaxies to the lower right.
