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]
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 ...
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 Most Distant Mature Galaxy Cluster [13] taken with ESO's Very Large Telescope in Chile and with NAOJ's Subaru Telescope in Hawaii. 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.
Angel numbers are a series of digits that can help you focus your attention or predict what might be coming down the metaphorical road. One of the steadiest angel numbers is 1212, which symbolizes ...
The cluster is slowly moving in the direction of the feet of what is currently the constellation of Orion. Like most open clusters, the Pleiades will not stay gravitationally bound forever. Some component stars will be ejected after close encounters with other stars; others will be stripped by tidal gravitational fields.
