    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]

    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. [7] 3266: Horologium Supercluster: Reticulum: 04 h 31 m 11.9 s: −61° 24′ 23″ 2 I-II 3341: 05 h ...

    These four near-equals at the core of galaxy cluster CL 0958+4702 are in the process of merging. [147] 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 ...

    Composite image of five galaxies clustered together just 600 million years after the Universe's birth [1]. A galaxy cluster, or a cluster of galaxies, is a structure that consists of anywhere from hundreds to thousands of galaxies that are bound together by gravity, [1] with typical masses ranging from 10 14 to 10 15 solar masses.

    Consists of at least 15 clusters plus other interconnected filaments. It is the most massive galaxy supercluster discovered so far. [19] Big Ring (2024) 1,300,000,000 Made up of galaxy clusters. (Theoretical limit) 1,200,000,000 Structures larger than this size are incompatible with the cosmological principle according to all estimates. However ...

    These are globular clusters within the halo of the Milky Way galaxy. The diameter is in minutes of arc as seen from Earth. For reference, the J2000 epoch celestial coordinates of the Galactic Center are right ascension 17 h 45 m 40.04 s, declination −29° 00′ 28.1″.

  9. List of open clusters - Wikipedia

    en.wikipedia.org/wiki/List_of_open_clusters

    This is a list of open clusters located in the Milky Way. An open cluster is an association of up to a few thousand stars that all formed from the same giant molecular cloud . There are over 1,000 known open clusters in the Milky Way galaxy, but the actual total may be up to ten times higher. [ 1 ]
