Halley's Comet Has A Long, Strange History As A "Supernatural" Celestial Object
People Thought The Comet Would Fill Our Atmosphere With Deadly Cyanogen In 1910
It's understandable for people to be afraid of something they don't understand, but in 1910, people were really, really freaked out about Halley's Comet. For the most part, scientists and civilians were fine with the idea of the comet. They hosted "comet parties," and treated the celestial body as a passing dignitary.
When scientists discovered the tail of the comet contained cyanogen, however, French astronomer Camille Flammarion jumped to conclusions and stated the gas “would impregnate the atmosphere and possibly snuff out all life on the planet.” Smooth move, Flammarion.
Obviously, people freaked out. They thought armageddon was here. Everyone started buying gas masks, and a few entrepreneurial folks began selling "Anti-Comet Pills." Scientists tried to explain how Flammarion's theory was impossible, but no one listened. In the end, gas failed to impregnate the atmosphere, and the comet continued on its path.
An Amateur Astronomer Believed The Comet Would Set Earth On Fire
1910 was a frightening year for amateur astronomers. With the coming of Halley's Comet, people began to fear for the worst and a bunch of wild theories cropped up about what could happen when the comet came around. One amateur astronomer, Sze zuk Chang Chin-liang, wrote a letter to the Engineer-in-Chief of the General Post Office in Greenwich to tell him the Earth was probably going to be burned to a crisp when the comet passed through the solar system again.
He believed the comet was transparent, convex, and had two distinct poles. He thought once the comet got between the Earth and the Sun, it would magnify the Sun's rays and cook the inhabitants of the planet. His letter arrived from Shanghai two years after Halley's Comet passed the Earth, and we remained unburnt.
Some People Believe Halley's Comet Was The Star Of Bethlehem
The problem with being the most famous comet in the solar system is that everyone projects their personal beliefs onto you. It's been speculated that Halley's Comet was the "star" the three wise men followed in order to find Jesus, but it doesn't really fit the timeline.
It's likely Jesus was born during sometime between 6 and 4 BCE, which doesn't work with the comet's timeline, as it appeared in both 164 BCE and 87 BCE. This doesn't mean the wise men didn't see a comet - it just wasn't Halley's Comet.
The Comet May Have Caused A Decade-Long Winter Starting In 536 CE
According to some researchers, around the year 536 CE a decade-long winter began, and it had something to do with Halley's Comet. Scholars in Europe and Asia at the time reported 536 CE and the following years were absolutely freezing. Their writings describe what sounds like a large celestial body passing across the Sun. This caused a deep freeze, which completely destroyed crops and lead to years of famine.
Geologist Dallas Abbott believes that on its trip past the Sun, Halley's Comet broke up; the resulting pieces of debris that fell to Earth created a large dust cloud, effectively blocking out the sun. An analysis of Greenland ice in 2013 from 533 - 540 CE shows "large amounts of atmospheric dust during this seven-year period, not all of it originating from Earth," according to Abbott.
Researchers also believe it could have been the reason humanity was more vulnerable to "Justinian's plague" from 541-542 CE. That being said, there's still quite a lot of research to do before we can place blame for this theoretical freeze on the comet.
Genghis Khan Believed It Was His "Personal Star"
Genghis Khan was the founder of the Mongol Empire, a vast army of disparate nomadic tribes, whose rule extended across modern-day China, Korea, the Caucasus, Central Asia, and substantial portions of Eastern Europe and Southwest Asia. When Halley's orbited in 1222 CE, Khan supposedly took inspiration from the comet and believed it was his "personal star." He decided to follow the comet west into southeastern Europe and continue the growth of his empire.
Mark Twain's Life Eerily Mirrored The Comet's Orbit
Mark Twain was an anomaly. Not just because his writing was able to beautifully encapsulate every day life, or because he somehow always had a perfectly tailored white linen suit. He was also one of the few people whose life lined up nearly exactly with Halley's Comet.
He was born two weeks after the comet appeared in 1835, and he passed when it returned in 1910. Of his relation to the comet, he said:
"I came in with Halley’s Comet in 1835. It is coming again next year, and I expect to go out with it. It will be the greatest disappointment of my life if I don’t go out with Halley’s Comet. The Almighty has said, no doubt: ‘Now here are these two unaccountable freaks; they came in together, they must go out together."
He died one day after the comet soared through the sky.
