...answer lies in a special report that goes to the White House this week. Called "The Nation's Energy Future," it is the result of a crash effort by a Government task force headed by Dixy Lee Ray, chairman of the Atomic Energy Commission. Given an extremely tight schedule-Nixon requested in June that a blueprint of energy research and development needs be delivered to him by Dec. 1-Ray's team tapped all available sources: Government agencies, private corporations and scientific institutions. After sifting the suggestions, it came up with guidelines for the U.S.'s research...
...escape from the bizarre objects, how can astronomers prove that they really exist? The answer may lie in the constellation Cygnus (The Swan), where scientists are now almost certain that they have located a black hole. Its presence was hinted at in 1971 by the first earth-orbiting X-ray satellite Uhuru, which detected a strong and widely fluctuating flow of X rays from Cygnus. Scientists suspected that the radiation source, which they named Cygnus Xl, was a pulsar, or neutron star, the result of a different form of stellar collapse. But the uneven fluctuations bore no resemblance...
...suggested that if a black hole were orbiting a larger, visible star, it would draw gases from the star. As those gases spiraled toward the black hole, they would collide, compress and heat up to as high as 100 million degrees-enough to produce an intense flow of X rays. Recent findings by NASA'S new Copernicus earth satellite strongly support this scenario. Cygnus X-l shows a sharp decrease in X-ray emissions every 5.6 days. That, according to optical astronomers, seems to be the time it takes the bright star's unseen companion to make...
