    The second most massive galaxy cluster next to El Gordo is RCS2 J2327, a galaxy cluster with the mass of 2 quadrillion suns. Also has a systematic designation of ACT-CL J0102-4915. [6] [7] [8] Musket Ball Cluster: Named in comparison to the Bullet Cluster, as this one is older and slower galaxy cluster merger than the Bullet Cluster.

    Comprises such a huge amount of mass that the galaxy cluster noticeably curves spacetime around it, making it into a gravitational lens. Smaller galaxies behind the cluster appear distorted into long, warped arcs around the cluster’s edges.

    These four near-equals at the core of galaxy cluster CL 0958+4702 are in the process of merging. [149] Galaxy protocluster LBG-2377: z=3.03 This was announced as the most distant galaxy merger ever discovered. It is expected that this proto-cluster of galaxies will merge to form a brightest cluster galaxy, and become the core of a larger galaxy ...

    MACS J0152.5-2852 is a massive galaxy cluster. Almost every pixel seen in the image is a galaxy, each containing billions of stars. [1]Galaxy groups and clusters are the largest known gravitationally bound objects to have arisen thus far in the process of cosmic structure formation. [2]

    Abell divided the clusters into six "richness groups", depending on the number of galaxies in a given cluster that lie within the magnitude range m 3 to m 3 +2 (the average number of galaxies per cluster for the entire catalog was 64): Group 0: 30–49 galaxies; Group 1: 50–79 galaxies; Group 2: 80–129 galaxies; Group 3: 130–199 galaxies
