Since gamma-rays cannot penetrate the atmosphere, the telescopes are detecting the particles created when gamma-ray photons collide with the atmosphere. Optical telescopes can then image the display the secondary particles make when passing through the atmosphere. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/New_Array/New_Array.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
