XKCD published an infographic a few weeks ago, showing 786 known exoplanets (planets orbiting suns other than our own) in our Milky Way galaxy, and the Planetary Habitability Laboratory has released an interactive version of that map. Go to the interactive map.

Our neighbor Andromeda Galaxy (also known as M31), 2.5 million light-years away and spanning some 260,000 light-years. It took 11 different image fields from the Galaxy Evolution Explorer (GALEX) satellite’s telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light.
