Old Globular Clusters

Caption

Old globular clusters (ages up to 10 billion years or more) are indicated by the red dots. These globular clusters are randomly distributed around the giant galaxy at the center of the Perseus galaxy cluster; this galaxy is the large gray to white oval at the center of the picture. Round or oval objects, also colored gray to white, are smaller galaxies that are part of the same galaxy cluster.
