- The University of Utah operates a cosmic ray detector called the Fly’s Eye II, situated at the Dugway Proving Ground about an hour’s drive from Salt Lake City. The Fly’s Eye consists of an array of telescopes which stare into the night sky and record the blue flashes which result when very high energy cosmic rays slam into the atmosphere. From the height and intensity of the flash, one can calculate the nature of the particle and its energy.
