The discovery of a new type of astronomical object—emitting very high energy gamma rays—has been announced by a team of scientists from Case Western Reserve University, Cleveland, Ohio, and the University of Melbourne, Australia.
Two discrete sources of such rays have been detected in the southern Milky Way in the direction of the galactic center. Gamma rays have been detected in the past by satellite as coming from the direction of the galactic center. The American-Australian measurements increased the resolution of the sources by about twenty times; enough, they feel, to indicate discrete sources. While gamma-ray sources were first detected by the American-Australian team in balloon flights made in 1969, extensive analysis by the group, much of it with computers, was needed to reveal their presence.
