The Andromeda galaxy (M31) is the closest big galaxy to our Milky Way. At 2.5 million light-years away, it’s the most distant thing you can see with the eyes alone, and, if you're in a reasonably dark location, now is the time to look for it, just to the East (right) and below the constellation Cassiopeia, which is currently in the Northeast sky and looks like the letter "W" rotated 90 degrees counterclockwise. Without a telescope, the Andromeda galaxy will look like a white smudge about the size of a full moon.
