M104: The Sombrero Galaxy
Explanation : 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 .
