Comets, often called ‘dirty snowballs,’ aren’t just icy wanderers. They’re cosmic oddballs responsible for some of the most bizarre and impactful events in our solar system and beyond. Get ready to explore ten of the craziest comet moments ever recorded!
A Comet Older Than the Solar System Landed on Earth
Imagine holding a piece of space history older than the planets themselves. That’s exactly what happened when scientists discovered a fragment of a pre-solar system comet embedded within a meteorite in Antarctica.
This tiny speck, born from the same dust disk that eventually formed the planets, offers a rare glimpse into the materials that swirled around in space long before our solar system existed. It’s like having a time capsule from the universe’s early days! [1]
We Pass Through Halley’s Comet Debris Every Year
Halley’s Comet, famous for its 76-year appearances, might seem like a distant visitor. But Earth actually encounters its dusty remains twice a year, creating mesmerizing meteor showers.
Each April to May, the Eta Aquariid meteor shower graces our skies, followed by the Orionid shower in October. These celestial displays are caused by Earth passing through Halley’s Comet’s dust trail, offering a spectacular show for skywatchers. [2]
A Missing Space Lander Was Found Wedged Inside A Comet
The Philae lander’s mission to Comet 67P was ambitious, but its landing didn’t go as planned. After bouncing into a shadowed crevice, Philae went silent, leaving its fans wondering about its fate.
Nearly two years later, the Rosetta space probe located Philae stuck inside a crack on the comet. Though upside down and unable to recharge, finding Philae brought closure to its dedicated followers. [3]
The Comet That Carved the Sudbury Basin
Canada’s Sudbury Basin, a massive oval-shaped crater, is the second-largest impact site on Earth. For years, its origin remained a mystery until scientists discovered the culprit: a giant comet.
The collision, which occurred approximately 1.8 billion years ago, created a crater initially much larger than the current basin. Erosion eventually reduced it to its present size, but the impact remains a testament to the power of cometary collisions. [4]
A Comet That Spews Booze
Comet Lovejoy isn’t your average icy rock; it’s a cosmic cocktail party! In 2015, as it passed by the Sun, Lovejoy began releasing ethyl alcohol—the same stuff found in your favorite drinks.
At its peak, Lovejoy spewed the equivalent of 500 bottles of wine every second. This boozy comet also released sugar and organic molecules, bolstering the theory that comets may have seeded Earth with the ingredients for life. Cheers to that! [5]
Was a Comet Responsible for the Demise of the Dinosaurs?
The asteroid impact in Mexico is widely blamed for the extinction of the dinosaurs. However, some researchers believe a comet might have been the real culprit.
The argument centers on the amount of material ejected during the impact. Proponents of the comet theory suggest that a smaller, faster comet would better explain the observed evidence. The debate continues, with scientists divided into “Team Comet” and “Team Asteroid.” [6]
A Comet Massacre in Space
Astronomers were shocked to discover a star system, Fomalhaut, surrounded by a staggering number of comets. This wasn’t just a few comets; it was a full-blown massacre.
Around 83 trillion comets orbit Fomalhaut, with approximately 2,000 collisions occurring daily. The constant crashes create a dust ring around the star, painting a picture of cosmic chaos. [7]
The Comet That Grew Bigger Than The Sun
In 2007, Comet Holmes briefly outshone the Sun. Normally a small object, Holmes unexpectedly released massive amounts of dust and gas, creating a coma (atmosphere) larger than our star.
At its peak, the coma measured 1.4 million kilometers in diameter, dwarfing the Sun. The cause of this massive eruption remains a mystery, but it provided a spectacular sight for skywatchers worldwide. [8]
The Comet That Defies Explanation
Comets are typically icy bodies with tails formed by the Sun’s heat. But Comet C/2014 S3 shattered this definition by showing no tail at all.
Dry and rocky, C/2014 S3 resembled an asteroid but possessed a comet-like orbit. This hybrid object left scientists scratching their heads, unsure whether it was a tailless comet, an asteroid from the Oort cloud, or something else entirely. [9]
The Comet That Vaporized A Village
Around 12,800 years ago, a comet airburst destroyed the ancient village of Abu Hureyra in Syria. Archaeologists initially missed the cosmic connection, but subsequent research revealed the devastating truth.
The comet fragmented in the atmosphere, causing a powerful explosion that vaporized the village and left behind nanodiamonds, melted glass, and carbon spheres. The event likely transformed the hunter-gatherer community into successful farmers. [10]
Comets continue to surprise and mystify us with their volatile behavior and profound impact on our solar system. From delivering life’s building blocks to causing catastrophic destruction, these ‘dirty snowballs’ hold secrets that scientists are still working to uncover.
