Located in the constellation Andromeda can be
found M31, the famous Andromeda Galaxy. This spectacular object
is a spiral galaxy similar to our own Milky Way. At a distance
of only 2 million light-years, it is one of the closest galaxies
to our own. Its enormous diameter of 200,000 light-years gives
it a visual magnitude of 3.5, making it the brightest galaxy in
the sky and the only galaxy visible to the naked eye. It can
easily be seen with binoculars, and telescopes will bring out
some of the galaxy's detail.
