This new image shows the results of a vast collision between two galaxies. This strange object is known as NGC 7252, or Arp 226, and has the odd nickname Atoms-for-Peace. The picture was taken by the Wide Field Imager on the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile. It is a combination of exposures taken through blue and red filters, for a total exposure time of more than 4 hours. The field of view is about 18 arcminutes across.
