What's going on in the center of this spiral galaxy? Named the Sombrero Galaxy
for its hat-like resemblance, M104 features a prominent
dust lane and a bright halo of stars and globular clusters.
Reasons for the Sombrero's
hat-like
appearance include an unusually large and extended central bulge of stars, and
dark prominent dust lanes that appear in a disk that
we see nearly edge-on. Billions of old stars cause the diffuse glow of the extended
central bulge visible in the above image from the 200-inch Hale Telescope. Close
inspection of the central bulge shows many points of
light that are actually globular clusters.
M104's spectacular dust rings harbor many younger and brighter stars, and
show intricate details astronomers don't yet fully
understand. The very center of the Sombrero glows across the electromagnetic
spectrum, and is thought to house a large black hole. Fifty
million-year-old light from the Sombrero Galaxy can
be seen with a small telescope towards the constellation
of Virgo
