M84

M84 = NGC4374 ( 12h 25.1m +12°53´, 9.3 mag. )
This elliptical galaxy in Virgo was discovered by Messier on March 18, 1781. Located near the centre of Virgo cluster some 55 million ly away, it measures 100,000 ly across.

M84 and M86 may be elliptical galaxies or S0 galaxies. The jury is still out.

M84, M86, and M87: three more ellipticals, in a very rich region. M87 is the centre of the Virgo Cluster, and is one of the most luminous galaxies known.
M89: small elliptical, resembling M87 but fainter.
M90: nice spiral in same region as M89.

Proof of Black Hole In Galaxy M84
Even more compelling evidence for a supermassive black hole comes from radio studies. Using the Very Long Baseline Array"a continent-wide network of 10 radio telescopes"a U.S.

The constellation Virgo is the location of a small and dim galaxy known as M84. It was originally thought to be an elliptical galaxy. But more recent evidence suggests that is it actually a face-on lenticular galaxy.

For example, large elliptical galaxies such as M84 or M87 in the Virgo Cluster of galaxies are the children of large disc galaxies that smash together in what we call ‘major mergers'.

Some lenticular galaxies (abbreviated SO galaxies) include M84 (in Virgo), M85 (in Virgo), M86 (in Virgo), NGC 5866 (the Spindle Galaxy), and perhaps M102. Enchanted Learning®
