Intrigued, the Caltech team turned a larger telescope on the object to analyze its light. They were confident that the resulting spectrum, not unlike the band of colors that appears when sunlight is passed through a prism, would tell them a lot. "Once you have a star's spectrum," says Djorgovski, "you can determine its temperature, its heavy elements and how fast it's moving with respect to Earth...
DIED. NATHANIEL KLEITMAN, 104, pioneer sleep expert at the University of Chicago and discoverer, with associates, of REM sleep in 1953; in Los Angeles. Kleitman's studies--on dream-sleep deprivation, the effect of sunlight on slumber--established sleep research as a separate, significant medical field...
...vaporized in an accident, they explain, would be so diluted in the atmosphere that it would pose no real threat to most people. Still, activists say, had Cassini been equipped with solar panels for electricity, all danger could have been averted. But Saturn receives only a hundredth of the sunlight Earth does, and the solar panels needed to supply Cassini at that distance would have to be far too large for such a mission. Other than plutonium generators, says physicist James Van Allen, discoverer of Earth's radiation belts, "there is no practical source of electrical power for spacecraft that...
