Clusters containing zero-metallicity red dwarfs or brown dwarfs ( possibly created by pair-instability supernovae ) have been proposed as dark matter candidates ,, but searches for these and other MACHO's through gravitational microlensing have produced negative results.

Clusters of Excellence have been conceived to contribute importantly to the respective university ’ s strategic planning and to accelerate the process of setting thematic priorities at universities.

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

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 ).

MySQL Clusters has a few important concepts behind its design, which add both benefits and burdens.

Besides various university institutions, non-university research institutions and industrial partners also play a important role throughout the Clusters.

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.

Applewhite and Nettles then split their followers into small groups, which they referred to as " Star Clusters ".

Clusters were designed to better equip congregations and their leadership while building stronger relationships and accountability.

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.

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.
