At the fourth Compton Symposium on Gamma Ray Astronomy and Astrophysics, scientists from Northwestern University and the U.S. Naval Research Laboratory announced the unexpected discovery of two clouds of antimatter in the Milky Way Galaxy. The researchers termed the material "antimatter annihilation radiation." The team of researchers used NASA's Compton Gamma Ray Observatory to discover the clouds, which scientists could not fully explain. "The origin of this new and unexpected source of antimatter is a mystery," William R. Purcell of Northwestern University explained. The scientists postulated that the clouds might have resulted from starbursts, jets of material from a nearby black hole, or from the merger of two neutron stars. Attempting to explain the startling nature of the discovery, Charles D. Dermer of the U.S. Naval Research Laboratory said, "It is like finding a new room in the house we have lived in since childhood. And the room is not empty it has some engine or boiler making hot gas filled with annihilating antimatter. "
