cluster, in astronomy: see star clusterstar cluster, a group of stars near each other in space and resembling each other in certain characteristics that suggest a common origin for the group. Stars in the same cluster move at the same rate and in the same direction. .....

Recognition that galaxies are independent star systems outside the Milky Way came from a study of the Andromeda Galaxy (1926–29) by Edwin P. ..... Click the link for more information. .cluster A group of stars whose members are sufficiently close to each other to be physically associated. Clusters range from dense congregations of many thousands of stars to loose groups of only a few stars. Current theories of stellar evolution suggest that stars form in associations, whose densest groupings remain bound as clusters while the other stars disperse; this view is supported by the relatively well-defined Hertzsprung–Russell diagrams of clusters, which indicate that cluster members are of essentially the same composition and age (see also turnoff point). Because the stars in a cluster are all at approximately the same distance, the observed differences in appearance are believed to be due mainly to differences in mass. An estimate of distance is obtained from the technique of main-sequence fitting. See globular cluster; open cluster.
Cluster An ESA mission to study in three dimensions the shape and dynamic behavior of small-scale structures in the Earth's plasma environment. In effect, Cluster is examining ‘space weather’ – that is, the interaction between the particles of the solar wind and the Earth's magnetosphere. The mission consists of four identical 500-kg satellites, carrying the same 10 instruments. The satellites were carried into space in two pairs by Russian-made Soyuz rockets during the summer of 2000. The first pair, nicknamed Salsa and Samba, were launched July 16, followed by the second pair, Rumba and Tango, launched Aug. 9. The Cluster craft were scheduled to operate until 2005. The mission, which was designated Cluster II, was the replacement for an earlier failed mission. The original Cluster satellites were to have been sent into space together in June 1996, on an Ariane-5 rocket, but were destroyed when the rocket unexpectedly tilted and broke up soon after liftoff.ClusterAny configuration of elements that are grouped or gathered closely together.cluster[′kləs·tər] (astronomy) star cluster (computer science) In a clustered file, one of the classes into which records with similar sets of content identifiers are grouped.

The term may imply resilience to failure and/orsome kind of load balancing between the servers. CompareRAIS.cluster (file system)An elementary unit of allocation of a diskmade up of one or more physical blocks.
A file is made up of a whole number of possiblynon-contiguous clusters. The cluster size is a tradeoffbetween space efficiency (the bigger is the cluster, thebigger is on the average the wasted space at the end of eachfile) and the length of the FAT.cluster(1) Two or more systems working together. See clustering.
(2) Also called an "allocation unit" or "file allocation unit," it is a number of storage sectors treated as a unit. A cluster is the smallest unit of storage the operating system's file system can manage. That means if a 1KB file is stored in a system with a 4KB cluster (see table below), the 1KB file takes up 4KB of disk space.
Following are the cluster sizes for the various Windows file systems starting with Windows XP. When FAT32 came out, the reduction of cluster sizes from 16KB and 32KB down to 4KB saved a lot of space for small files. See file system, FAT, FAT32 and lost cluster.
