After remaining silent about the discovery for seven months, the Cambridge team published its findings and tentative conclusions in Nature, setting off a flurry of activity among U.S. scientists. Focusing Cornell University's giant radio telescope near Arecibo, Puerto Rico, on the one pulsar whose position was given by the British, Astronomer Frank Drake confirmed the rapid, regular signal and discovered that it was ten times as powerful at 111 MH (for megahertz: 1,000,000 cycles per second) than at any other frequency. "This has been the biggest bombshell that I can remember in radio astronomy," he says...
Oftentimes Overdone. U.S. scientists have already devised a host of theories about pulsars. Yeshiva University Astrophysicist A.G.W. Cameron and Caltech Astronomer John B. Oke believe the mysterious objects may be white dwarfs, Cameron suggesting that their frequency of oscillation is actually a harmonic of the lower frequency assigned to dwarfs by current theory. U.S. Naval Research Physicist Herbert Friedman of the U.S. Naval Research Lab oratory and Cornell Astronomer Thomas Gold support the neutron-star hypothesis. Gold speculates that the first pulsar identified may be an extremely dense body as small as six to 60 miles in diameter that rotates...
