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.
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. The Perseus Cluster, for example, has more than a thousand galaxies and is one of the most luminous sources of X-rays in the sky.
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.

Galaxy clusters are the largest gravitationally bound objects in the universe. They have three major components: Dark matter, a mysterious form of matter that has so far escaped direct detection with any type of telescope, but makes its presence felt through its gravitational pull on the galaxies and hot gas.
