62 million light-years from here, you could watch one of the largest scale collisions that occurs in our Universe: 2 Galaxies Colliding.
The Antennae galaxies are shown in this image. It's made from 3 of NASA's great Observatories -- the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).
Much could be said about this image, but I think it's best to let the Universe speak for itself on this one.
