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 catalogue comprises nearly all of the most spectacular examples of the five types of deep-sky object – diffuse nebulae, planetary nebulae, open clusters, globular clusters, and galaxies – visible from European latitudes. Furthermore, almost all of the Messier objects are among the closest to Earth in their respective classes ...
Home to over 100,000 stars,the cluster is notable for containing a large number of variable stars (112) and pulsars (8), including one double neutron star system, M15-C. It also contains Pease 1, the first planetary nebula discovered within a globular cluster in 1928. [12] [13] Just three others have been found in globular clusters since then. [14]
Messier 28 or M28, also known as NGC 6626, is a globular cluster of stars in the center-west of Sagittarius. It was discovered by French astronomer Charles Messier in 1764. [ 11 ] [ a ] He briefly described it as a "nebula containing no star... round, seen with difficulty in 3 1 ⁄ 2 -foot telescope; Diam 2 ′ ."
Messier 2 or M2 (also designated NGC 7089) is a globular cluster in the constellation Aquarius, five degrees north of the star Beta Aquarii. It was discovered by Jean-Dominique Maraldi in 1746, and is one of the largest known globular clusters.
Messier 56 (also known as M56 or NGC 6779) is a globular cluster in the constellation Lyra. [ a ] It was discovered by Charles Messier in 1779. [ b ] It is angularly found about midway between Albireo (Beta (β) Cygni) and Sulafat (Gamma (γ) Lyrae).
Charles Messier noted it in 1764 and—a studier of comets—cast it as one of his nebulae. William Herschel was the first to resolve individual stars in the cluster in 1791, counting roughly 200. [9] Messier 5 is receding from the Solar System at a speed over 50 km/s. [10]
