Scientists using the 305-m dish antenna at the Arecibo Observatory in Puerto Rico had discovered a pulsar-a pulsating radio source-orbiting a companion celestial object in the constellation Aquila, the New York Times reported. Both pulsar and the object weighed as much as the sun but were only a few kilometers in diameter. It was the first pulsar discovered circling another object, a phenomenon which made it possible for scientists to estimate its mass. Its orbit had been calculated from the slight variations -in its pulse rate. While it was possible that the companion was a black hole, scientists thought it more likely that both were neutron stars and a search was continuing to find out if the companion was a very weak pulsar.
