The photograph, taken by the Advanced Camera for Surveys (ACS) shows a tumultuous collision between four galaxies located 1 billion light-years from Earth. The galactic wreckage is creating a torrent of new stars. The tangled-up galaxies, called IRAS 19297-0406, are crammed together in the centre of the picture. IRAS 19297-0406 is part of a class of galaxies known as ultraluminous infrared galaxies (ULIRGs). ULIRGs are considered the progenitors of massive elliptical galaxies. ULIRGs glow fiercely in infrared light and appear 100 times brighter than our Milky Way Galaxy.
