The Sombrero Galaxy from HST
Explanation: Why does the Sombrero Galaxy look like a hat? Reasons include the
Sombrero
's 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. Close inspection of the bulge in the
above
photograph
shows many points of light that are actually
globular clusters
.
M104
's spectacular
dust ring
s 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
