...Astrophysicist Richard Henry and his NRL associates crammed X-ray detectors into the nose of an Aerobee rock et last September and fired it high above the atmosphere, which absorbs X rays before they reach the earth. Telemetry from one detector designed to spot "soft" or low-energy X rays emanating from intergalactic space showed unexpectedly high readings. What- in apparently empty space - was producing this radiation...
Meanwhile, pulsar theories continued to proliferate beyond the pulsating neutron-star and white-dwarf-star theories first suggested by Cambridge astronomers. Princeton Astrophysicist Jeremiah Ostriker suggested that the signals might be caused by rapidly rotating white dwarfs with a local disturbance on their surfaces. Signals from the disturbance would sweep across the earth like a lighthouse beacon once during each rotation of such a star. British Astrophysicists Fred Hoyle and J. Narlikar propose that the signals are connected with supernovas, or exploding stars...
...flight from Amsterdam to Paris in 1965, French Astrophysicist Jacques Blamont had a sad tale to tell his traveling companion. Because of faulty equipment, every photographic plate of groups of stars exposed during a complex and expensive balloon-borne telescope experiment had been hopelessly blurred. The companion, University of Michigan Electrical Engineer George Stroke, was less discouraged. "Don't throw anything away," he urged Blamont. "Give me time and I'll get pictures out of your ruined film...
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...
