...character that neither could have trained for, and that neither could have predicted would undo the Speaker rather than the President. Even as Gingrich set to sharpening the blades of the guillotine, his adversary stayed on message, made peace in the Middle East, waved John Glenn back into orbit and watched the Dow follow close behind, as Gingrich produced an impeachment spectacle that left voters gagging, and a budget that drew the same response from his own party. By the time the routine midterm election had dissolved into a humiliating defeat Tuesday at the polls, it was suddenly Gingrich whose...
...Leonids, so named because they seem to radiate from the constellation Leo, are actually debris shed by comet Tempel-Tuttle. In an elongated, 33-year orbit of the sun, the comet travels as far out as Uranus, then back to within 91 million miles of the solar surface, passing close to Earth's orbit on both its way in and its way out. Like other comets, Tempel-Tuttle is, in effect, a dirty snowball that heats up as it approaches the sun and boils off some of its "dirt," which consists largely of particles, some pea size...
These particles, called meteoroids, remain in orbit and gradually disperse along the comet's orbital path, forming a giant, debris-laden stream in space. In its yearly travels around the sun, Earth intersects with or comes close to that stream every November, and sightings of the Leonids have been recorded in texts as far back as A.D. 902. The speeding meteoroids hurtle into Earth's atmosphere, are heated by friction and become blazing meteors that are incinerated in midair...
...crew of the shuttle Discovery was apparently smart enough to come in out of a storm, returning safely to Earth last Saturday before the Leonid meteor shower could begin. The mission's glamour boy, however--veteran astronaut John Glenn--was a bit unsteady, both in orbit and on his return to terra firma...
While Senator and first-American-to-orbit-Earth John Glenn once again gained national attention last week--this time for his role as a geriatric guinea pig aboard the space shuttle Discovery--Dr. Charles A. Czeisler, professor of medicine at Harvard Medical School (HMS), was busy investigating Glenn's sleep patterns...
