M104, also known as The Sombrero Galaxy, lies in the constellation Virgo at a distance of approximately 29 million light years.  The galaxy has a very large central bulge and a prominent dust band that extends around the circumstance of its spiral disk.  A very large, and massive, halo surrounds M104.  This feature is more indicative of an elliptical galaxy than a typical spiral galaxy.  Studies based on observations made using the Hubble Space Telescope and the Canada-French-Hawaii Telescope have determined a super massive black hole resides in M104’s core.  This massive black hole is estimated to have a total mass of approximately 1 billion times that of our Sun.
