(Virgo A, NGC 4486, Virgo X-1, UGC 7654, Messier 87)
(supergiant elliptical galaxy in local universe)
M87 (for Messier 87, also Virgo A,
NGC 4486, Virgo X-1, or UGC 7654) is the
second brightest galaxy in the northern Virgo Cluster,
about 53 million light-years away.
It is a featureless elliptical galaxy, but does
have many orbiting globular clusters,
and has a relativistic jet,
which includes a feature of interest, a bright
spot (of varying brightness) designated HST-1.
M87's supermassive black hole, M87*, has been a target of the Event Horizon Telescope
and has been imaged.
