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 ...
Globular cluster: Nearest globular cluster to the Earth. Also the first globular cluster known to have exoplanets (PSR B1620-26b) Messier 12: 74.4 [28] Messier 70: 68 [29] NGC 290: 66 [30] Open cluster: Messier 28: 60 [31] Globular cluster: Messier 18: 52.4 [32] Open cluster: The following notable star clusters are listed for the purpose of ...
The Milky Way [c] is the galaxy that ... About 40% of the Milky Way's clusters are on retrograde orbits, ... Open clusters are also located primarily in the disk.
NGC 7790 is a young open cluster [1] of stars located some 10,800 [2] light years away from Earth in the northern constellation of Cassiopeia.At this distance, the light from the cluster has undergone extinction from interstellar gas and dust equal to E(B – V ) = 0.51 magnitude in the UBV photometric system.
You would think that it would be easy to spot a cosmic structure as enormous as a supercluster holding legions of galaxies, but not so -- the Milky Way can hide all kinds of objects, usually due ...
Citizen scientists spotted an object zipping through the Milky Way at more than 1 million miles an hour, and a new study shows it could be a rare hypervelocity star. ... stars in globular clusters ...
In the Milky Way galaxy, globular clusters are distributed roughly spherically in the galactic halo, around the Galactic Center, orbiting the center in highly elliptical orbits. In 1917, the astronomer Harlow Shapley made the first respectable estimate of the Sun's distance from the Galactic Center, based on the distribution of globular clusters.
