The Andromeda galaxy is in the constellation Andromeda.  It is the closest galaxy to our Milky Way galaxy, 2.5 million light years.  Scientists believe in the two galaxies will collide in 4 to 5 billion years.  The Andromeda galaxy is visible to the in the night sky with binoculars. This image was captured in my backyard with a telescope and dedicated astrophotography camera.
