The Andromeda Galaxy, M31, is approaching the Milky Way and will collide with it
in 4.7 billion years.  It is approximately 2.5 million light years, 780,000
parsecs, from our galaxy now.

The color images show the full central region and its dust lanes. 
The galaxy is a spiral inclined to our line of sight. 
The nucleus of the galaxy is the bright spot in its center. Within that there is
a central black hole ~10^8 (100,000,000) times the Sun's mass.
