An international team, including researchers from the Instituto de Astrofísica de Canarias (IAC) and Universidad de La Laguna (ULL), has detected the formation of a very remote galaxy from the violent collision of two other galaxies The data, obtained by NASA and ESA space telescopes, and by terrestrial telescopes, contradict a commonly-held theory that explains the formation of massive galaxies from the agglomeration of smaller galaxies over time When the Universe was three or four million year old it was already populated with massive red elliptical galaxies containing old stars.
