A Look Skyward at Halley's Comet : Griffith Observatory Prepares for a Celestial Visitor

The comets were at any time

Signs of God's ire and signify

Storm, famine, plague and heavy floods;

Earthquakes and changes, Death of Lords.

--17th-Century German hymn

While most of the mysticism and terror that surrounded the appearance of comets in earlier times has been dissipated by greater scientific knowledge today, public wonderment over these periodic celestial visitors endures.

Today, the most famous of these interplanetary streaks of ice and dust, Halley's Comet, is practically at the Earth's doorstep, hurtling toward the planet at about 120,000 miles per hour. About 277 million miles away from the Earth at the beginning of September, it will close to 148 million miles away by Oct. 15.

There are few places where the comet discovered by Edmond Halley (pronounced like "galley," not like "gaily") will flash more brightly into the public consciousness than at the Griffith Observatory.

"Comet season opens today," said E.C. Krupp, the observatory's director, on Wednesday. The opening of a new planetarium show, "Comet Halley's 1986 World Tour," coincided with the Sept. 11 flyby of the International Comet Explorer spacecraft past the Comet Giacobini-Zinner.

The Human Bond

Krupp said that in its planetarium show and other Halley-related activities, the observatory will stress the human bond with Halley's Comet that has made its appearance eagerly awaited throughout the years.

"You hear about Halley's Comet when you are a child and learn that it comes back every 76 years," Krupp said. "Everyone hears that and calculates how old they will be when it returns."

"Comet Halley is a once in a lifetime experience," said Stephen Cooperman, a staff lecturer at the observatory. "It binds us to our ancestors."

According to John Mosley, program supervisor at the observatory and producer and writer of the planetarium show, it is the "linking of generations"--tales of sightings handed down from parent to child--that make the comet's appearance meaningful to the mass public, not its brightness in the sky.

"You don't see New Year's Eve, but you celebrate its passage because you know it's there," said Mosley, who first began to think about the comet's 1985-86 appearance nearly 30 years ago when he was nine years old.

The upcoming passage of the comet will be less spectacular than it was in 1910 because it is not coming as close to the Earth on this trip, according to Mosley. "It will not be served up on a platter," Krupp said.

The comet will not be visible from Los Angeles because the city lights bleach out the sky, making faint objects, such as comet tails, impossible to see. "If you can't see the Milky Way, you won't be able to see the comet," Mosley said.

Contrary to popular opinion, the problem of lights obscuring Halley's Comet is not unique to the current passage. Wrote E. E. Barnard, a foremost authority on Halley's Comet during its 1910 passage, in the Astrophysical Journal of June, 1914: "The great cities that have grown up since 1835, and the smoke and electric lights of today completely robbed the comet of its glory when seen by dwellers in and near the centers of population."

Compared with earlier times, the world of 1910 took a fairly sanguine attitude toward Halley's Comet. Although some authorities warned that the Earth could be contaminated by poison gases from the tail of the comet (a fear that some hucksters profited from by selling comet pills to worried citizens), many others celebrated the comet's appearance.

A "Halley's Comet Rag" was composed, the Ziegfeld Follies developed a comet dance and plush hotels across the United States and Europe celebrated by holding rooftop comet parties.

In earlier days, comets were considered omens, usually of natural disasters or the death of kings.

Said the Chroniques de l'Oeil-de-Boeuf of the Comet of 1680: "While the fearful are making their wills and leaving their goods to the monks in expectation of the end of the world, there is high agitation at the court on the question as to whether this wandering star has not come to announce the death of some great personage."

Said an anonymous chronicler of the Comet of 837, which came during the reign of Louis the Debonir of France: "A phenomenon which is always ominous and a carrier of bad news appeared in the sky. As soon as the emperor, who always had paid attention to such events, had noticed it, he allowed himself no rest.

" 'A change of reign and the death of a prince are announced by this sign,' he told me. He consulted the bishops, who advised him to pray, build churches and found monasteries. Which he did. But he died three years later."

Mosley said the planetarium show is also a tribute to Halley, who also prepared the first star charts of the southern sky, tested the first underwater diving bell, developed the first annuity tables, discovered the distance between the Earth and the Sun, and invented weather charts.
