Number 94 (Story #2), September 16, 1992 by Phillip F. Schewe and Ben Stein A NEUTRON IMAGE OF THE SUN has been produced using the Compton Telescope on board the Gamma Ray Observatory. Comptel usually records gamma rays, but on this occasion---a solar flare occurring on 15 June 1992---the influx of neutrons was measured. The resultant picture represents the first time a celestial object has been imaged by particles rather than electromagnetic radiation. (Sky & Telescope, October 1992.)
