Star Clusters
by members of the Wells & Mendip Astronomers
Star clusters come in two types: Open clusters (a clump of new born stars slowly drifting apart) and globular clusters (an ancient structure of old stars, perhaps the remnant of a dwarf galaxy absorbed by the Milky Way). Globular clusters are large enough to be observable also in nearby galaxies such as in the Andromeda Galaxy
