...Federal Office of Coal Research has helped to sponsor four pilot plants, and eight more are planned. Each uses a different system, but all are based on a complicated process that was pioneered in Germany in 1936. The technique starts by breaking down water into its components of hydrogen and oxygen. The hydrogen is combined in the presence of heat with the carbon in pulverized coal to produce methane, the main ingredient of natural...
...fadeout from public view, Comet Kohoutek was far from a scientific disappointment. About a month after they had detected methyl cyanide molecules in the comet's head, radio astronomers atop Kitt Peak last week reported picking up the "signature" of hydrogen cyanide molecules in radio waves from Kohoutek. The discovery has dual significance. Both molecules have been found in the clouds of gases and dust in the vast reaches between the stars; thus their presence in the comet lends strong support to the theory that comets were formed from the same interstellar material out of which the solar system...
Before the encounter, Astronaut Carr spotted a puzzling red color in the comet's tail. That may mean that Kohoutek has more moisture than most comets, for this tint suggests concentrations of hydrogen and oxygen, the two components of water. In other respects, Kohoutek's twin tails-one composed of dust particles, the other of glowing gases -seem to be developing normally. As the comet began its hairpin turn round the sun, the dust tail blown by the slight pressure of sunlight continued to trail behind. But the plasma tail, interacting with the solar wind, moved...
...Such clouds may become Jovian in proportions, with a diameter of more than 100,000 miles, though they are very thinly dispersed. In 1969 and 1970, NASA'S Orbiting Astronomical Observatory (OAO-2) discovered that the coma of comets is surrounded by a still larger ball of wispy hydrogen that may far exceed the sun's diameter of 860,000 miles...
...hydrogen cloud is believed to be formed from the dissociation of water molecules in the nucleus. As the comet nears the sun, it acquires its most characteristic feature. Bombarded steadily by the charged particles of the solar wind and by the slight but measurable pressure of sunlight itself, the cometary gases and dust are swept back to form one or more glowing tails. These may reach lengths of 60 million miles or more, roughly two-thirds the distance between earth and sun. Regardless of the direction of the comet's travels, its tail is always directed away from...
