Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy in the constellation Virgo that contains several ...
The Virgo Cluster is a cluster of galaxies whose center is 53.8 ± 0.3 Mly (16.5 ± 0.1 Mpc) [2] away in the constellation Virgo.Comprising approximately 1,300 (and possibly up to 2,000) member galaxies, [3] the cluster forms the heart of the larger Virgo Supercluster, of which the Local Group (containing the Milky Way galaxy) is a member.
Discovered in 2014, it was found escaping the supergiant elliptical galaxy Messier 87, [3] in the Virgo Cluster. [1] It is one of thousands of globular clusters found in M87. [4] It is the first hypervelocity star cluster so far discovered. [5] The globular is located at decimal degrees (RA, DEC) (187.72791°, +12.68295°). [1]

Charles Messier. The first edition of 1774 covered 45 objects (M1 to M45).The total list published by Messier in 1781 contained 103 objects, but the list was expanded through successive additions by other astronomers, motivated by notes in Messier's and Méchain's texts indicating that at least one of them knew of the additional objects.
