Galaxy cluster - Wikipedia
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.

List of galaxy groups and clusters - Wikipedia
This article lists some galaxy groups and galaxy clusters. Defining the limits of galaxy clusters is imprecise as many clusters are still forming. In particular, clusters close to the Milky Way tend to be classified as galaxy clusters even when they are much smaller than more distant clusters.

Galaxy groups and clusters - Wikipedia
Clusters of galaxies are the most recent and most massive objects to have arisen in the hierarchical structure formation of the Universe and the study of clusters tells one about the way galaxies form and evolve.

Large Scale Structures - NASA Science
Galaxy clusters contain many more galaxies, from hundreds to thousands. The Coma cluster, for example, houses over 1,000 individual galaxies and stretches over 20 million light-years across.

Galaxy Clusters - Harvard–Smithsonian Center for Astrophysics
Galaxy clusters are the largest objects in the universe that are held together by their own gravity. They contain hundreds or thousands of galaxies, lots of hot plasma, and a large amount of invisible dark matter.

Exploring galaxy groups and clusters and their brightest galaxies ...
Each coloured circle depicts a galaxy group or cluster. The richest galaxy clusters are marked in red; these are the richest galaxy clusters in the Hercules and Leo superclusters. The...

A clear view of a galaxy cluster - ESA/Hubble
Observing galaxy clusters like Abell 3322 can advance our understanding of the evolution and interactions of dark and luminous matter in galaxy clusters, and also reveals powerful gravitational ‘telescopes’ that magnify distant objects through gravitational lensing.

Galaxy Cluster: Definition, Names and Examples, Supercluster, Facts
Galaxy clusters are the largest known structures in the universe, held together by gravity. These groupings contain hundreds to thousands of galaxies spanning millions of light-years. Cluster masses range from 10^14 to 10^15 solar masses, with dark matter comprising 85% of the total mass.

NASA SVS | Galaxy Clusters
Explore how individual galaxies assemble into colossal cosmic communities. The first galaxies emerged a couple hundred million years after the Big Bang. Over time, individual galaxies assembled into sizable groups, which scientists refer to as galaxy clusters.

Cluster of galaxies | Galactic Structure, Formation & Evolution ...
Cluster of galaxies, Gravitationally bound grouping of galaxies, numbering from the hundreds to the tens of thousands. Large clusters of galaxies often exhibit extensive X-ray emission from intergalactic gas heated to tens of millions of degrees.
