M81 and M82
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a
spiral galaxy about
12 million
light-years away in the
constellation
Ursa Major. Due
to its proximity to
Earth, large size and
active galactic nucleus (which harbors a
supermassive black hole), Messier 81 has
been studied extensively by professional astronomers. The
galaxy's large size and relatively high brightness also make it a popular target
for
amateur astronomers.
