Monster Galaxy Pileup
7 August 2007
Astronomers have combined data from the WIYN 3.5-meter telescope on Kitt Peak and NASA’s Spitzer and Chandra space telescopes to identify one of the biggest collisions of galaxies ever observed. Four large galaxies have been spotted in the process of tangling and, ultimately, merging into single gargantuan galaxy five billion light-years from Earth.
