M104: The Sombrero Galaxy

The famous Sombrero galaxy (M104) is a bright nearby spiral galaxy.
The prominent dust lane and halo of stars and globular clusters give this galaxy its name
. Something very energetic is going on in the Sombrero's center, as much X-ray light
has been detected from it. This X-ray emission coupled with unusually high central
stellar velocities cause many astronomers to speculate that a black hole lies at the
Sombrero's center - a black hole a billion times the mass of our Sun.
