A supercluster is a large group of smaller galaxy clusters or galaxy groups; [1] they are among the largest known structures in the universe. The Milky Way is part of the Local Group galaxy group (which contains more than 54 galaxies), which in turn is part of the Virgo Supercluster , which is part of the Laniakea Supercluster , which is part ...
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.
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]
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 ...
This gravitational focal point, in the case of Laniakea, is called the Great Attractor, and influences the motions of the Local Group of galaxies, where the Milky Way galaxy resides, and all others throughout the supercluster. Unlike its constituent clusters, Laniakea is not gravitationally bound and is projected to be torn apart by dark energy ...
The Coma Cluster lies at the core. [22] [23] Sloan Great Wall (SDSS Great Wall) 2003 z=0.07804 433 Mpc long This was the largest known galaxy filament to be discovered, [22] until it was eclipsed by the Hercules–Corona Borealis Great Wall found ten years later. Sculptor Wall (Southern Great Wall, Great Southern Wall, Southern Wall) 8000 km/s long
Supergalaxy, super-galaxy, or super galaxy may refer to: Astronomy. a term for the Virgo Cluster of galaxies and its outlying members;
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).
