Random Thread: June 2014

Late in May, astronomers rushed to their telescopes after the Swift satellite spotted what looked like a huge explosion called a gamma-ray burst in the galaxy next door to ours, known as M31 or Andromeda. It turned out to be a false alarm (fortunately for any living creatures in large parts of Andromeda). But Andromeda is still a beautiful galaxy and well worth looking at. What’s more, someday all of those stars will be even closer neighbors: Andromeda and our own Milky Way galaxy are rushing toward each other and will merge into one galaxy in a couple of billion years.
