DIED. DAVID SCHRAMM, 52, bold, influential astrophysicist whose studies of dark matter shed new light on the birth of the universe; after crashing his two-engine plane near Denver...
...Irwin Shapiro is an imaginative and broad-ranging astrophysicist who has greatly advanced our knowledge of the universe while also helping both teachers and students to reach a deeper understanding of the nature of scientific thought," said President Neil L. Rudenstine in a statement...
...surface. Using computer techniques similar to those required to produce sonograms of the human body, the scientists followed the sun's sound waves as they raced through its interior and across its surface at speeds of 20,000 m.p.h. "It's a terrible din," says University of Cambridge astrophysicist Douglas Gough. But, he adds, since millions of explosions are taking place at any single moment, their waves can be plotted like a body scan to create a three-dimensional image of the sun's interior extending down to its huge core, which accounts for 70% of the star's volume...
...sneakers. Freshly groomed and shod, Foale was nothing if not upbeat when he talked to NASA boss Daniel Goldin, himself under heat for allowing Americans to continue working aboard the 11-year-old Mir. "The safety concerns, I think, are well met," said the 40-year-old British-born astrophysicist, "and I'm not worried...
...real mystery, scientists say, is not that the positrons were created. It's that they were lobbed so many thousands of light-years above the galactic plane, like water droplets scattered by a giant geyser. Scientists offered several competing explanations last week. Rice University astrophysicist Edison Liang thinks black holes may be the key. While most of the stuff that falls into a black hole stays there, he observes, some of it gets blasted out in the form of a hot wind. Liang's hypothesis draws strength from the fact that there appear to be a good half a dozen...
