Clusters which have enough mass to be gravitationally bound once the surrounding nebula has evaporated can remain distinct for many tens of millions of years, but over time internal and external processes tend also to disperse them.

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

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 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.

Clusters of patients with Chuvash polycythemia have been found in other populations, such as on the Italian island of Ischia, located in the Bay of Naples.

Clusters of trigger points are not uncommon in some of the larger muscles, such as the gluteus group ( gluteus maximus, gluteus medius, and gluteus minimus ).

Clusters of boron are boranes such as pentaborane and decaborane.

However, other earlier patented technologies, such as that from Manteia ( acquired by Solexa ), which generate DNA on a solid phase surface by bridge amplification-are generally referred to as " Clusters ".

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 averaging 75 to 80 individuals live together in complex systems of burrows in arid African deserts.

Through random linking between star Clusters, this construction allows universes of 5, 000 star systems or more to be generated.

Clusters are allocation units for data on various file systems ( FAT, NTFS, etc.

High availability clusters ( HAC ) improve application availability by failing them over or switching them over in a group of systems — as opposed to High Performance Clusters, which improve application performance by running them on multiple systems simultaneously.

Clusters amplify the signal of aposematic coloration, and individuals may participate in group regurgitation or displays.

* Clusters of consonants may be simplified, producing silent letters e. g. silent ⟨ th ⟩ in asthma, silent ⟨ t ⟩ in Christmas.

The New General Catalogue of Nebulae and Clusters of Stars ( abbreviated as NGC ) is a well-known catalogue of deep sky objects in astronomy compiled by John Louis Emil Dreyer in 1888, as a new version of John Herschel's Catalogue of Nebulae and Clusters of Stars.

Clusters consist of geographical areas.

The Jewel Box Clusters is a Shapley class g and Trumpler class I 3 r cluster ; it is a very rich, centrally-concentrated cluster detached from the surrounding star field.

Clusters correspond generally to the concept of an " object " in an OO language, and have roughly the same syntax.

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

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.

* Gravitational lensing: Clusters of galaxies contain enough matter to distort the observed orientations of galaxies behind them.

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.

Their Catalogue of One Thousand New Nebulae and Clusters of Stars was published in 1786.
