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.
It consisted of two known rich clusters and one newly discovered cluster as a result of the study that discovered it. The then known clusters were Cl 1604+4304 (z=0.897) and Cl 1604+4321 (z=0.924), which then known to have 21 and 42 known galaxies respectively. The then newly discovered cluster was located at 16 h 04 m 25.7 s, +43° 14′ 44.7 ...
MACS J0416.1-2403 or MACS0416 abbreviated, is a cluster of galaxies at a redshift of z=0.397 with a mass 160 trillion times the mass of the Sun inside 200 kpc (650 kly).Its mass extends out to a radius of 950 kpc (3,100 kly) and was measured as 1.15 × 10 15 solar masses. [2]
The Phoenix Cluster (SPT-CL J2344-4243) is a massive, Abell class type I galaxy cluster located at its namesake, southern constellation of Phoenix.It was initially detected in 2010 during a 2,500 square degree survey of the southern sky using the Sunyaev–Zeldovich effect by the South Pole Telescope collaboration.

Abell 262 is a galaxy cluster in the Abell catalogue. It is part of the Perseus–Pisces Supercluster , one of the largest known structures in the universe. [ 4 ] Although its central galaxy, NGC 708 , is a giant cD galaxy , most of its bright galaxies are spirals , which is unusual for a galaxy cluster. [ 4 ]
The supercluster's discovery was reported in December 2016 by Kraan-Korteweg et al. through an analysis of the redshifts of 4500 galaxies from the combined data of the 2dF Galaxy Redshift Survey which uses the AAOmega fiber optics from the Anglo-Australian Observatory (AAO), and the South African Large Telescope (SALT).
Draco Supercluster (SCL 114) is a galaxy supercluster in the constellation Draco. [1] [2] [3] It is located at a distance of 300 Mpc h −1 on a side of a void of diameter of about 130 Mpc h −1. The near side of the void is bordered by the Ursa Major supercluster.
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]
