Clusters are not a syntactic language construct, but rather a standard organizational convention.

Clusters of galaxies are often dominated by a single giant elliptical galaxy, known as the brightest cluster galaxy, which, over time, tidally destroys its satellite galaxies and adds their mass to its own.

Clusters are then formed relatively recently between 10 billion years ago and now.

Clusters are larger than groups, although there is no sharp dividing line between the two.

Clusters are quite prominent in X-ray surveys and along with AGN are the brightest X-ray emitting extragalactic objects.

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.

Clusters have two important properties: their masses are large enough to retain any energetic gas ejected from member galaxies and the thermal energy of the gas within the cluster is observable within the X-Ray bandpass.

Clusters such as the Pleiades, Hyades and a few others within about 500 light years are close enough for this method to be viable, and results from the Hipparcos position-measuring satellite yielded accurate distances for several clusters.

Clusters are also a crucial step in determining the distance scale of the universe.

He waited until 1802 ( in Catalogue of 500 new Nebulae, nebulous Stars, planetary Nebulae, and Clusters of Stars ; with Remarks on the Construction of the Heavens ) to announce the hypothesis that the two stars might be " binary sidereal systems " orbiting under mutual gravitational attraction, a hypothesis he confirmed in 1803 in his Account of the Changes that have happened, during the last Twenty-five Years, in the relative Situation of Double-stars ; with an Investigation of the Cause to which they are owing.

Clusters of galaxies should not be confused with star clusters such as galactic clusters and open clusters, which are structures within galaxies, as well as globular clusters, which typically orbit galaxies.

NGC 2000. 0 ( also known as the Complete New General Catalog and Index Catalog of Nebulae and Star Clusters ) is a 1988 compilation of the NGC and IC made by Roger W. Sinnott, using the J2000. 0 coordinates.

The first major update to the NGC is the Index Catalogue of Nebulae and Clusters of Stars ( abbreviated as IC ), published in two parts by Dreyer in 1895 ( IC I, containing 1, 520 objects ) and 1908 ( IC II, containing 3, 866 objects ).
