M80 (NGC 6093)
M80 (NGC 6093) is one of the densest known globular clusters in the Milky Way Galaxy; it lies in the constellation Scorpius. M80 contains hundreds of thousands
of stars, including a large population of blue
stragglers in its core. The cluster has been the site of two known novae:
in 1860 (T Scorpii) and in 1938. M80 was discovered by Charles Messier on Jan. 4, 1781. Though not very conspicuous, M80 can be located easily
as it is lies almost exactly halfway between Antares (Alpha Scorpii) and Graffias (Beta Scorpii), just below the declination
parallel of Dschubba (Delta Scorpii).
