M104/NGC 4594 Galaxy,  is a peculiar galaxy of unclear classification. M104’s diameter is 50,000 Ly about 1/3 the size of our own Milky Way.  This Galaxy is 31.1 Mly from earth, shinning at magnitude 8. It reside in the constellation of Virgo, near Corvus. M104 has many globular clusters, estimated to be nearly 2,000 in number — 10 times more than the number of globular clusters in our Milky Way galaxy.        

M 1o4’s core is very illuminated, where a one-billion-solar-mass black hole resides. This galaxy has an estimated mass of 800 billion stars similar to our own sun. M104 is one of the most massive objects in the Virgo galaxy cluster.

M104/NGC 4594 Galaxy was discovered on May 11, 1781 by Pierre Méchain,

Charles Messier made a hand-written note about this and five other objects (now collectively recognized as M104 – M109) to his personal list of objects now known as the Messier Catalogue. It was not included until 1921  about the 10 years after Mt. Wilson’s 100” telescope was up and running (1917)
