An open cluster is a type of star cluster made of tens to a few thousand stars that were formed from the same giant molecular cloud and have roughly the same age. More than 1,100 open clusters have been discovered within the Milky Way galaxy, and many more are thought to exist. [1]
Open clusters are often dominated by hot young blue stars, because although such stars are short-lived in stellar terms, only lasting a few tens of millions of years, open clusters tend to have dispersed before these stars die. A subset of open clusters constitute a binary or aggregate cluster. [2]
The open cluster Messier 6 in the constellation Scorpius is also known as the Butterfly Cluster or NGC 6405. This is a list of open clusters located in the Milky Way. An open cluster is an association of up to a few thousand stars that all formed from the same giant molecular cloud. There are over 1,000 known open clusters in the Milky Way ...
Map showing the location of NGC 752. NGC 752 (also known as Caldwell 28) is an open cluster in the constellation Andromeda.The cluster was discovered by Caroline Herschel in 1783 and cataloged by her brother William Herschel in 1786, although an object that may have been NGC 752 was described by Giovanni Batista Hodierna before 1654.
The Collinder catalogue is a catalogue of 471 open clusters compiled by Swedish astronomer Per Collinder.It was published in 1931 as an appendix to Collinder's paper On structural properties of open galactic clusters and their spatial distribution.
Tr / Trumpler — Robert Julius Trumpler's open cluster list, published in Preliminary results on the distances, dimensions and space distribution of open star clusters; Tu — Tucker (double stars) Turner — David G. Turner (?) (open star clusters) (for example: Turner 9 at and near the variable star SU Cygni, aka 'SU Cygni cluster')
Open Cluster Framework (OCF) is a set of standards for computer clustering. The project started as a working group of the Free Standards Group , now part of the Linux Foundation . Original supporters included several computing companies and groups, including Compaq , Conectiva , IBM , Linux-HA , MSC Software , the Open Source Development Lab ...
M46 and M47 are two open clusters in the same binocular field. M47 can be seen with the naked eye under dark skies, and its brightest stars are 6th magnitude. Messier 93 (M93) is another open cluster somewhat to the south. NGC 2451 is a very bright open cluster containing the star c Puppis, and the near NGC 2477 is a
