The Halley’s Comet Panic of 1910: When a Streak in the Sky Sparked Global Chaos
In 1910, the world was undergoing profound changes. Europe was brimming with militarism and revolutions, while the United States was weathering a minor depression. Yet, amidst these significant global events, it was a streak in the sky that captured humanity's imagination—and fear. Halley’s Comet wasn’t merely an astronomical wonder; to many, it was a harbinger of doom.

This cosmic spectacle became the center of one of history's most bizarre panics, fueled by a potent mix of ancient superstitions, misunderstood science, and sensationalist headlines. Enter The Halley's Comet Panic of 1910.
Fear of the Unknown: Humanity’s Longstanding Suspicion of Comets
For centuries, comets have been seen as omens of disaster. Ancient civilizations believed they heralded wars, famines, or death, while Romans referred to them as "bearded stars," often linking their appearance to divine wrath or the end of a ruler's reign.
Even as science began to shed light on these celestial phenomena, fear persisted. Historical accounts, such as Halley’s Comet's depiction in the Bayeux Tapestry in 1066, tied these events to monumental tragedies like King Harold’s defeat at the Battle of Hastings. The arrival of Halley’s Comet in 1910 reignited these ancient anxieties on a global scale.
The Cyanide Gas Panic: When Science Met Sensationalism
The fear surrounding Halley’s Comet in 1910 was amplified when astronomers revealed that Earth would pass through its tail. French astronomer Camille Flammarion speculated that the comet's tail contained toxic cyanogen gas, adding that it might "possibly snuff out all life on the planet." Although Flammarion later clarified that this was a mere thought experiment, newspapers ran with the most alarming parts of his statement.
Headlines warned of impending doom, sparking mass hysteria. People rushed to buy gas masks, “anti-comet pills” (nothing more than sugar tablets), and even comet-proof umbrellas. Some individuals created makeshift oxygen tanks, convinced they could survive by blocking the deadly gases.
The media frenzy also led to absurd reassurances, such as the claim that Halley’s Comet could “fit inside a suitcase.” This attempt to calm the public backfired, with satirical responses mocking the astronomers' packing skills.
The World Reacts: Panic, Faith, and Opportunism
The panic manifested in many ways. Some religious leaders declared the comet a sign of the end times, urging their congregations to repent. In Oklahoma, a cult called the Select Followers even prepared to sacrifice a 16-year-old girl to appease divine forces and prevent the apocalypse. Thankfully, law enforcement intervened just in time, thwarting the tragic ritual.
In urban centers, scammers profited from the chaos. A Kansas vendor sold “comet insurance policies,” while a California conman marketed metal bowls as “comet shields.” In New Orleans, self-proclaimed voodoo doctors peddled anti-comet potions. Wealthier families, believing they could escape doom, boarded private yachts to “ride out the apocalypse” at sea.
Amid the madness, humorous and tragic stories abounded. In Spokane, a prank involving a fire balloon caused mass panic, while in New York, a young girl tragically fell to her death during a rooftop comet party. Meanwhile, in California, a man crucified himself, believing it was the only way to survive the comet’s wrath.
Cultural Impact: How the 1910 Panic Shaped Humanity’s View of the Cosmos
Despite the chaos, Halley’s Comet also inspired wonder. In some cultures, it was celebrated with reverence. Indigenous communities in Canada performed ceremonial dances, while observatories in London and Paris hosted comet-viewing parties that turned fear into fascination.
The comet’s 1910 appearance became a cautionary tale about the dangers of misinformation and sensationalism, leaving a lasting legacy in popular culture. It served as a reminder of humanity’s dual nature—oscillating between fear and curiosity when faced with the unknown.
What If It Happened Today?
It’s easy to laugh at how a glowing dot in the sky once incited such madness. But let’s be honest—would we react any differently if a comet came hurtling toward Earth tomorrow?
