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.
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]
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. Smaller galaxies behind the cluster appear distorted into long, warped arcs around the cluster’s edges ...
This galaxy filament contains the Perseus–Pisces Supercluster. Pisces–Cetus Supercluster Complex (1987) 1,000,000,000: Contains the Milky Way, and is the first galaxy filament to be discovered. (The first LQG was found earlier in 1982.) A new report in 2014 confirms the Milky Way as a member of the Laniakea Supercluster.
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.
Tr / Trumpler — Robert Julius Trumpler's open cluster list, published in Preliminary results on the distances, dimensions and space distribution of open star clusters; Tu — Tucker (double stars) Turner — David G. Turner (?) (open star clusters) (for example: Turner 9 at and near the variable star SU Cygni, aka 'SU Cygni cluster')
The brightest cluster galaxy of the Bootes Cluster (ACO 1930), an elliptical galaxy at B1950.0 14 h 30 m 6 s +31° 46′ apparent magnitude 17.8, was found by Milton L. Humason in 1936 to have a 40,000 km/s recessional redshift velocity. [196] [198] [199] LEDA 20221 (MCG+06-16-021) Brightest cluster galaxy 1932 – z = 0.075 (V = 23000 km/s)
The Local Supercluster (LSC or LS), or Virgo Supercluster is a formerly defined supercluster containing the Virgo Cluster and Local Group, which itself contains the Milky Way and Andromeda galaxies, as well as others. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years).
