Messier 59 (also known as M59 or NGC 4621) is an elliptical galaxy in the constellation Virgo.
History [ edit ]
Messier 59 and the nearby elliptical galaxy
Messier 60 were both discovered by Johann Gottfried Koehler in April 1779 during observations of a comet in the same part of the sky. [4 ] Charles Messier listed both in the Messier Catalogue about three days after Koehler's discovery. [4 ]
One supernova (1939B) has been recorded in M59; it reached a peak magnitude of 11.9.
Characteristics [ edit ]
Messier 59's core contains a
supermassive black hole, with a mass that has been estimated to be 270 million times the mass of the Sun, and counter-rotates with respect of the rest of the galaxy, being bluer. [6 ] This galaxy also has an inner disk of stars [7 ] [8 ] and is very rich in [9 ] globular clusters, with a population of them that has been estimated in around 2200. [10 ]
