Sombrero Galaxy – Messier 104

The Sombrero Galaxy lies within a cloud of galaxies that extends to the south of the Virgo Galaxy Cluster. It lies approximately 29 million light years distant, and has a linear diameter of 130,000 light years.

Based on the stellar dynamics in its core, a research group demonstrated in the 1990s that a supermassive black hole, 1 billion times the mass of the Sun, is present in the center of the Sombrero Galaxy.
This galaxy's most striking feature is the massive dust band that cuts across its nucleus and encloses the central bulge. The dust band also contains most of the galaxy's cold hydrogen gas, and is the primary site of star formation within the galaxy.
