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]
SMACS J0723.3–7327, commonly referred to as SMACS 0723, is a galaxy cluster about 4 billion light years from Earth, [2] within the southern constellation of Volans (RA/Dec = 110.8375, −73.4391667).
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.
RCS2 J2327 (also identified as RCS2 J2327-0204) is an extremely massive galaxy cluster.It is located approximately 6.4 billion light-years away in the constellation of Pisces, [2] thus making it one of the farthest clusters away from Earth.
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 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]
The Pisces–Cetus Supercluster Complex is estimated to be about 1.0 billion light-years (Gly) long and 150 million light years (Mly) wide. It is one of the largest structures known in the observable universe, but is exceeded by the Sloan Great Wall (1.3 Gly), Clowes–Campusano LQG (2.0 Gly), U1.11 LQG (2.5 Gly), Huge-LQG (4.0 Gly), and Hercules–Corona Borealis Great Wall (10 Gly ...
