Thatcher drew large crowds during her sightseeing expeditions, including visits to an apartment complex in suburban Krylatskoye and a well-stocked supermarket, where the PM purchased a can of herring-like fish fillets called pilchards. The Prime Minister also met with Physicist Andrei Sakharov, the dissident leader who was allowed to return to Moscow four months ago from a seven-year exile in Gorky. Sakharov emphasized the importance of Gorbachev's social reforms to the prospects for world peace. Said he: "A more democratic, more open country is safer for the world as a whole...
Another report in last week's Nature, while not dealing with 1987A, provided further insight into Type II supernovas. A group led by Chemist Edward Anders and Physicist Roy Lewis, both of the University of Chicago, revealed that they had discovered an abundance of submicroscopic diamonds in a meteorite that fell in Mexico in 1969. While the impact of a meteor slamming into the earth creates enough pressure to crystallize carbon into diamonds, the tiny samples found by the Chicago team apparently resulted from an ancient supernova. The evidence: they contained atomic forms of the gas xenon different from...
...allowing a five-minute viewing window of the southern skies before falling back to earth. A third: "Everyone who has got an instrument in his closet is digging it out and petitioning NASA for support to go to Australia and fly it in a balloon," says Marvin Leventhal, a physicist with AT&T's Bell Labs. Leventhal and his collaborator Crawford MacCallum, a physicist with the Sandia Corp., already have their balloon, a plastic monster so huge (600 to 700 ft. tall) that its material could be used to cover the Washington Monument...
...also produces the ethereal neutrinos, which effortlessly zip through the star's outer layers and into space. Under these circumstances, there is a limit to how much the neutrons can be compressed. As gravity tightens its grip further, the neutrons, in what Hans Bethe, Cornell University's Nobel laureate physicist, has called the "moment of maximum scrunch," recoil ferociously...
...span of 13 seconds on Feb. 23, about three hours before light from the supernova was first observed. And data provided by the IMB (Irvine-Michigan- Brookhaven) detector under Lake Erie showed a burst of eight neutrinos in six seconds at the same time as the Japanese reading. Says Physicist Frederick Reines, of the University of California, Irvine: "One observation by one team is not sufficient; it has to be confirmed by an independent group. But together, the results from the IMB detector and the Kamiokande II detector are hard to disbelieve...
