That galaxy is careening towards us at hundreds of thousands of miles per hour. Because of that, it's one of the few galaxies that show blueshift instead of redshift. But don't worry, it won't crash into our galaxy for another three billion years or so.

Astronomers using NASA's Hubble Space Telescope have identified the source of a mysterious blue light surrounding a supermassive black hole in our neighboring Andromeda Galaxy (M31). Though the light has puzzled astronomers for more than a decade, the new discovery makes the story even more mysterious. The blue light is coming from a disk of hot, young stars that are whipping around the black hole in much the same way as planets in our solar system are revolving around the Sun. Rating: 5
