- The Andromeda Galaxy

or the Andromeda Galaxy, is an spiral galaxy that was once thought
to be a nebula. It is in actuality our closest galactic neighbor.
It is visible to the naked eye under good conditions as a small
fuzzy spot close to Pegasus in the constellation Andromeda (I promise
- I've seen it naked eye before). It is often studied as an example
of our own Milky Way galaxy and has the same characteristics of
our home galaxy. It is closely passed by M32, the smaller body of
stars in the lower part of the picture. It is apparent that these
two contestants recently passed by each other and this has displaced
the spiral in M31 a little bit.
