Messier 84
Messier 84 (also known as M84 or NGC 4374) is a lenticular galaxy in the constellation Virgo. M84 is situated in the heavily populated inner core of the Virgo Cluster of galaxies.[3]
Radio observations and Hubble Space Telescope images of M84 have revealed two jets of matter shooting out from the galaxy's center as well as a disk of rapidly rotating gas and stars indicating the presence of a 1.5 ×109 M☉[4] supermassive black hole.
History
Charles Messier discovered Messier 84 on 18 March 1781 in a systematic search for "nebulous objects" in the night sky.[5] The object is the 84th in the Messier Catalogue.
Supernovae
Two supernovae have been observed in M84: SN 1957[6] and SN 1991bg.[7] Possibly, a third, SN 1980I is part of M84 or, alternatively, one of its neighboring galaxies, NGC 4387 and M86.[8]
