Messier 60

Messier 60 or M60, also known as NGC 4649, is an elliptical galaxy approximately 57[4] million light-years away in the equatorial constellation of Virgo.

[6] The galaxy has an effective radius of 128″ (translating, at its distance, to about 10 kpc[6]), with an estimated mass of ~1012 M☉ within a threefold volume, of which nearly half is dark matter.

X-ray emission from the galaxy shows a cavity created by jets emitted by the hole during past active periods, which correspond to weak radio lobes.

[17] The motion of M60 through the intercluster medium is resulting in ram-pressure stripping of gas from the galaxy's outer halo, beyond a radius of 12 kpc.

[8] Messier 60 was the fastest-moving galaxy included in Edwin Hubble's landmark 1929 paper concerning the relationship between recession speed and distance.
