Astronomers conducting a three-year survey of ultra-luminous infrared galaxies (ULIRGs) have discovered more than 24 of them involved in three-, four-, or even five-galaxy smashups. Astronomers have made this discovery by analyzing Hubble telescope pictures of these pileups, including the nine presented here. These results offer a snapshot of what conditions were like in the early universe, when galaxy collisions were commonplace.
