M104-Sombrero Galaxy


The name of this galaxy speaks for itself and I find the most remarkable feature is the well-defined dark dust lane that bisects the galaxy.  Astronomers report that these dust particles, many of which are micron in size, comprise an estimated mass of at least 10 million suns.  Another amazing feature of this galaxy is the massive black hole at its center which contains an estimated thousand million solar masses.
