Messier 80 (also known as M80 or NGC 6093) is a globular cluster in the constellation Scorpius. It was discovered by Charles Messier in 1781, being one of his first discoveries. [9] This star cluster is, as to its angle from the solar system, midway between α Scorpii and β Scorpii in a field in the Milky Way Galaxy that is rich in nebulæ.

The Messier 80 globular cluster in the constellation Scorpius is located about 30,000 light-years from the Sun and contains hundreds of thousands of stars. [26] The count of known globular clusters in the Milky Way has continued to increase, reaching 83 in 1915, 93 in 1930, 97 by 1947, [19] and 157 in 2010.
The light curve of T Scorpii, plotted from measurements by Arthur von Auwers. T Scorpii, or Nova Scorpii 1860, was a nova in the globular cluster Messier 80 (M80). It was discovered on 21 May 1860 by Arthur von Auwers at Koenigsberg Observatory and was independently discovered by Norman Pogson on May 28 at Hartwell observatory.
Image taken by ESO's VISTA of the Globular Cluster VVV CL001. On the right lies the globular star cluster UKS 1 and on the left [where?] lies a much less conspicuous new discovery, VVV CL001. [1] The two are not physically located close to each other; this is a line-of-sight coincidence. [2] This is a list of globular clusters.
Messier 68, a loose globular cluster whose constituent stars span a volume of space more than a hundred light-years across. In 2005, astronomers discovered a new type of star cluster in the Andromeda Galaxy, which is, in several ways, very similar to globular clusters although less dense.
It is an Oosterhoff type II (OoII) globular cluster, which means it belongs to the group of metal-poor clusters with longer period RR Lyrae variable stars. The 1997 Catalogue of Variable Stars in Globular Clusters listed 28 candidate variable stars in the cluster, although only 20 have been confirmed. As of 2001, there are 17 known RR Lyrae ...
M13 is 22,200–25,000 light-years away from Earth, [9] and the globular cluster is one of over one hundred that orbit the center of the Milky Way. [ 17 ] [ 18 ] The stars in this cluster are firmly in the Population II category, markedly lower in metals than Population I stars like the Sun and most other stars in the Sun's close proximity.
