...likened the event to the detonation of a hydrogen bomb in an underground cavern: all matter moved to the fringes in the shape of a shell leaving the core relatively empty. Galaxies were the direct result of the separate waves in multiple explosions colliding, which caused a large deposit of high density matter, the scientists said...
...Mauna Kea Observatory in Hawaii, nearly 14,000 ft. above sea level, Astronomer Dale Cruikshank is using infrared photometry and imagery to measure the heat radiation from Halley's coma and the distribution of dust within it, as well as to look for certain isotopes of carbon and hydrogen. Says he: "I'm convinced there's some organic material in the comet...
Like dancers in an intricately choreographed ballet, each craft will perform a variety of tasks, complementing and aiding one another every thrust of the way. Japan's two probes, Sakigake (Pioneer) and Suisei (Comet), between them will study the solar wind and examine the hydrogen cloud surrounding the comet. The Soviet Union's Vega 1 and Vega 2 will analyze the abundant dust motes and charged gases that envelop the comet's nucleus. Most remarkable of all, data and pictures from the Vega twins will enable European scientists to chart Halley's course precisely enough to allow their probe, Giotto...
...members of a vast chemical family known as hydrocarbons, compounds composed of hydrogen and carbon entwined in complex and varying arrays. As it turns out, living creatures contain considerable stores of both elements. Putting two and two together, geologists have long assumed that when living organisms die, heat, light and bacteria begin to degrade the constituent compounds. That organic material then collects in sedimentary layers in the sea and is buried progressively deeper. After millions of years, pressure and temperature convert the debris into fossil fuels. Yet little hard evidence supports this conventional wisdom. Declares Tore Lindbo, Swedish Power Board...
...tubes terminate inside an airless 16-ft.-wide aluminum chamber, each entering it from a different direction. Inside, the focusing lenses are arrayed around a pellet of deuterium and tritium, two heavier varieties of hydrogen atoms. Scientists hope that when the beams simultaneously hit the pellet, which is smaller than a grain of sand, the temperature of the pellet's outer surface will be raised to 100 million degrees, causing it to vaporize explosively. Just as a rocket is pushed forward by its tail exhaust, the vaporizing surface would exert a force inward, compressing the pellet to a density...
