...fiery visitor is called Kohoutek (after its discoverer, Czech Astronomer Luboš Kohoutek- pronounced Loo-bosh Ko-hoe-tek); it promises to rival and perhaps surpass in brightness Halley's comet, which last appeared in 1910 and will not be seen again until 1986. By the time Kohoutek emerges from its passage behind the sun early in January, its tail should be full grown, a glittering streamer extending across as much as a sixth of the evening sky. There is some chance that Kohoutek will not live up to all its billing - comets are notoriously unpredictable. Some split into...
...intergalactic spaceship ("No warranties expressed or implied"). He says it will take off Dec. 24 before the comet's gases can ignite the earth's oil supply and bring death to most of mankind. UFO Cataloguer and Astronomer J. Allen Hynek, who was born under Halley's comet in 1910, is taking a more realistic view; he is bracing himself for a flood of calls at his Northwestern University UFO center from people worried about the fiery space spectacle...
...comet of 1456 and many of the others that influenced ancient history were one and the same: the celestial visitor that became known as Halley's comet. A 17th century protégé of Isaac Newton, Edmund Halley was convinced that comets travel, like planets, in closed orbits around the sun. Using his mentor's formulas, he calculated the paths of comets dating back to 1337 and found that three-those of 1456, 1531 and 1607 -had roughly the same orbit as the comet of 1682 (which he had seen as a young man). Halley concluded that...
...when it will appear in the morning sky. By early January, its tail-formed when the gases boiling off the comet are swept away from the sun by charged solar particles-may stretch across one-sixth of the evening sky. In fact, Kohoutek may glow many times brighter than Halley's comet, which blazed across...
...March by Czech-born Astronomer Luboš Kohoutek while he was looking for asteroids with the Hamburg Observatory's 31-in. Schmidt telescope; at that time it was some 480 million miles away from the sun, or roughly in the vicinity of the orbit of Jupiter. In contrast, Halley's comet-less bright than Kohoutek's-was not spotted until it was about 170 million miles closer to the sun. Although the nucleus of a typical comet (which is thought to be composed of frozen water, methane and ammonia, as well as dust particles) is only about...
