University of Utah physicists Gordon Thomson, Charlie Jui and John Matthews discuss the Telescope Array cosmic ray observatory's discovery of a "hotspot" -- located beneath the Big Dipper in the northern sky -- emitting an unusual number of ultrahigh-energy cosmic rays. The source of these rays, which are the most energetic particles in the universe, remains unknown, but the new finding will help narrow the search.
