Birth of Stars in Galactic Wreckage
The photograph, shows a tumultuous collision between four galaxies located 1 billion light-years from Earth. The galactic car wreck is creating a torrent of new stars. The tangled up galaxies, called IRAS 19297-0406, are crammed together in the center 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.
