Long since stripped of their electrons by the high temperatures, the nuclei of the hydrogen atoms slam together at tremendous speeds, fusing to form helium and releasing huge amounts of energy. Though the nuclear fires have been lit, the actual ignition is hidden deep within the interstellar clouds. "Nature very discreetly pulls the curtain over the act of birth," says Thaddeus. But the infant star soon makes its presence known, shining through and illuminating the obscuring cloud. This process is occurring in the Orion Nebula (see color page), the illuminated portion of a gigantic cloud of gas and dust that...
...then, its role as a great power had paradoxically placed the country in the position of opposing its own historic origins and libertarian roots. In addition, the impressive progress of its economy had led to the creation of formidable nuclei of economic power, not subject to the constitutional controls imposed by the system on the civil Government, that endanger the workings of democracy at its very foundations...
...optimistic. While it's true there is less public attention paid now to feminism than there once was, she says, a lot of women are working quietly on changing society, working for equal opportunity laws and welfare rights for unmarried mothers. "Women have moved out into very committed smaller nuclei, organizing through the community in which they live, in health care, schools, and so forth," she says. "They're not as raucous as they used to be, they're not doing anything the media could really pick up on. But at least they're presenting their material with a political...
Controlled energy from nuclear fusion-joining atomic nuclei instead of splitting them as in fission-still remains what it has been for a generation: a possibility. But in a number of laboratories and one private company-KMS Industries of Ann Arbor, Mich.-scientists are moving closer to doing what they know can be done: fusing the nuclei of deuterium and tritium to create a powerful burst of energy. At KMS and the Government's Los Alamos lab, lasers are being used to "implode" deuterium pellets. Energy has been produced, but not enough to be measured accurately or drive...
...comets both have nuclei of less than one kilometer, and do not have tails. They will both return toward earth in about six years...
