The Sombrero Galaxy (M104) was discovered on May 11, 1781, by French astronomer Pierre Méchain.
28 - 31 million light years from Earth. Roughly 50,000 light year in diameter, about half the size of the Milky Way.
The center hosts an extremely massive black hole (~ 1 - 9 billion solar masses), making it thousands of times more massive than the one in our galaxy.
M104 contains a massive system of nearly 2,000 globular clusters, significantly more than the Milky Way.
