NATIONAL GEOGRAPHIC SPECIAL (CBS, 7:30-8:30 p.m.). "The Hidden World" takes a look into the fascinating realm of insects, among them a Phasmida called the giant walking stick, which can grow up to 16 inches long, the goliath beetle, which is 4 inches long, and a swarm of locusts stretching for 23 miles...
...three months away. In 1899 and 1932, at the time of the November encounter, the main cluster was even farther away. Both times there were only disappointingly modest increases in the Leonid showers-partly because of the meteoroids' 33¼-year orbital period and partly because the main swarm had probably been pulled into a slightly different orbit as it passed close by Jupiter and Saturn...
This November, a full four orbits after 1833, things should be different. The main swarm of Leonids should be back at the same point where they were intercepted by the earth 133 years ago. Astronomers who have predicted a substantial, if not spectacular shower, are hopeful that the earth will again pass directly through 1866 I's biggest clump of orbiting debris...
...solid particles. Every year, in mid-November, the earth passes through this orbit, and some of these enter our atmosphere and burn up, producing a yearly shower of shooting stars. But the fantastic spectacle of 1833, as well as similar ones in 1799 and 1866, come from a large swarm of particles which only comes by every 33 years...
Unfortunately, astronomers the world over, trembling with anticipation, observed nothing unusual at the last two predicted returns. They concluded that the swarm had been de- flected slightly by the gravitational pulls of Jupiter and Saturn. No one knows if the orbit has now been shifted back. The only indication that it might have is that the regular yearly meteor shower has been steadily increasing for the last three years...
