Wide-field View of Interacting Galaxies: A 'Cosmic Joust' | DESI Legacy Survey

This wide-field view shows the region of the sky around a pair of interacting galaxies, nicknamed the 'cosmic joust', where one of them is piercing the other with intense radiation. The galaxies appear as a tiny white dot at the center of this image. The Atacama Large Millimeter/submillimeter Array (ALMA) resolved them in great detail, and the European Southern Observatory’s Very Large Telescope (VLT) studied the damage that one galaxy is inflicting on the other.
