NGC 520: Colliding Galaxies from Hubble
NGC 520 is a jumble of stars, gas, and dust, now thought to be the remains of two colliding disk galaxies. This Hubble Space Telescope image shows a band of intricately interlaced dust running vertically down the spine of the colliding galaxies. A similar collision might happen in a few billion years between our Milky Way and the Andromeda Galaxy.
