This montage shows three views of the distant group of interacting and merging galaxies called SPT2349-56. The left image is a wide view from the South Pole Telescope that reveals just a bright spot. The central view is from Atacama Pathfinder Experiment (APEX) that reveals more details. The right picture is from the Atacama Large Millimeter/submillimeter Array (ALMA) and reveals that the object is actually a group of 14 merging galaxies in the process of forming a galaxy cluster.
