Andromeda a.k.a M31 is nearly 2.5 million light-years away and is headed for our galaxy. It’s a very interesting object and scientists are continuously observing it. NASA’s Swift spacecraft, designed to locate exploding stars, recently took a very amazing picture in it’s X-Ray mode of Andromeda Galaxy. Between May 25 and July 26, 2008, Swift’s Ultraviolet/Optical Telescope (UVOT) acquired 330 images of M31 at wavelengths of 192.8, 224.6, and 260 nanometres.

Our galaxy, the Milky Way, is surrounded by many other small galaxies. Some of these include dwarf galaxies which are very small as compared to the Milky Way. In the past, these dwarf galaxies have been colliding with the Milky Way but because of its huge size Milky Way showed no significant change in its shape or behavior, so in short our galaxy is not likely to be destroyed by these small galaxies. The previous thoughts of colliding galaxies involved rip and tear motion but this actually happens if a big galaxy like the Andromeda collides with the Milky Way, only then havoc will be created. In fact, scientists think many satellite galaxies have already rammed into the Milky Way, though so far it has endured.

Earthlings! Get ready to pack your bags and leave… the planet! No, wait; leave the galaxy if you can!
The biggest galaxy in our galactic neighborhood, and the closest, Andromeda is on a cannibalism spree, consuming other galaxies as it moves, and leaving a path of destruction. And at a speed of 75 miles per second, it is headed our way!
