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.
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 ...
Shapley 20 Cluster: 03 h 30 m 34.6 s: −52° 33′ 12″ 3 I-II 3158: Shapley 17 Cluster: 03 h 42 m 39.6 s: −53° 37′ 50″ 2 I-II 3192: MCS/MACS J0358.8-2955 Eridanus: Comprises such a huge amount of mass that the galaxy cluster noticeably curves spacetime around it, making it into a gravitational lens.
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek galaxias, literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.

This is a list of largest galaxies known, sorted by order of increasing major axis diameters. The unit of measurement used is the light-year (approximately 9.46 × 10 12 kilometers). Overview
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]
