Observations from Chandra and other telescopes have captured a powerful cosmic event: two galaxy clusters have collided and are now poised to head back for another swipe at each other. Galaxy clusters are some of the largest structures in the Universe held together by gravity. In these images, X-rays from Chandra and ESA’s XMM-Newton have been combined with LOFAR data and an optical image from Pan-STARRs of the stars and galaxies in the field of view.
