Number 197 (Story #3), October 5, 1994 by Phillip F. Schewe and Ben Stein THE MOST ENERGETIC GAMMA BURST yet observed by the orbiting Gamma Ray Observatory was recorded on February 17, 1994. The burst's energy was calculated to be 25 GeV, many times more energetic than those previously measured. Furthermore, the burst was the longest ever, lasting more than an hour. This monster burst may have resulted from the collision of two stars. (Astronomy, November 1994.)
