M31-The Andromeda Galaxy

The Andromeda Galaxy is a giant neighbor to our own Milky Way Galaxy. It lies about 2.5 million light years away and is has about 125% of the mass of our Milky Way. Two small companion galaxies are seen in this photo, M32 below the main galaxy and M110 above.

The Andromeda Galaxy shines at a relatively bright magnitude of 4.4 making it an easy naked eye object from a dark sky.

This photo was taken on October 4, 2008 early in the morning. The sky was nearly perfect.
