Charles Messier discovered Messier 58, along with the elliptical galaxiesMessier 59 and Messier 60, on April 15, 1779.[14] M58 was reported on the chart of the Comet of 1779 as it was almost on the same parallel as the star Epsilon Virginis.[11][19] Messier described M58 as a very faint nebula in Virgo which would disappear in the slightest amount of light he used to illuminate the micrometer wires.[11][20] This description was later contradicted by John Herschel's observations in 1833 where he described it as a very bright galaxy, especially towards the middle. Herschel's observations were also similar to the descriptions of both John Dreyer and William Henry Smyth who said that M58 was a bright galaxy, mottled, irregularly round and very much brighter toward the middle.[11]
Like many other spiral galaxies of the Virgo Cluster (e.g. Messier 90), Messier 58 is an anemic galaxy with low star formation activity concentrated within the galaxy's optical disk,[21] and relatively little neutral hydrogen, also located inside its disk, concentrated in clumps,[22] compared with other galaxies of similar morphological type. This deficiency of gas is believed to be caused by interactions with Virgo's intracluster medium.
Messier 58 has a low-luminosity active galactic nucleus, where a starburst may be present[23] as well as a supermassive black hole with a mass of around 70 million solar masses.[24] It is also one of the very few galaxies known to possess a UCNR (ultra-compact nuclear ring), a series of star-forming regions located in a very small ring around the center of the galaxy.[25] This led to its being dubbed the "ring bearer galaxy" by the popular astronomy YouTube program "Deep Sky videos".[18]
SN 1989M (Type Ia, mag. 12.2) was discovered by Givi N. Kimeridze on 28 June 1989.[28][29][14] It was found 33 arcseconds north and 44 arcseconds west of M58's nucleus.[14]
