7 Christmas-Season Mysteries We Still Can’t Solve

There’s something about December that makes the world feel different. Maybe it’s the early sunsets, the way the cold settles into our homes, or the fact that winter holidays have always been tied to rituals, superstitions, and stories people swore were true. Christmas today is all cinnamon candles and Mariah Carey songs. But scratch the surface, and you’ll find so much more. So, let’s go back. Like way back, and explore the eight biggest Christmas season mysteries.

The Christmas Eve UFO Wave Over Belgium

There are holiday lights, and then there’s whatever the hell happened over Belgium in the winter of 1989-1990. Starting in late November, and hitting its apex on Christmas Eve, thousands of people, including police, pilots, and military personnel, witnessed huge, silent, triangular craft drifting over small towns.

These weren’t quick glances. They were long-duration sightings of massive objects with bright, geometric lights that didn’t flicker or blink. The Belgian Air Force was so concerned about the intrusion into national airspace that they scrambled F-16 fighter jets. The pilots locked onto the objects with their radar—and then instantly lost contact. The crafts executed impossible maneuvers and accelerated faster than any publicly known aircraft could move.

To this day, the Belgian UFO Wave is considered one of the most credible and baffling mass-sightings in modern history. Whatever was flying over those quiet European towns, it defied every known law of physics.

The Unsolved Fate of the Starving Time Settlers at Jamestown

While Thanksgiving usually gets the colonial focus, the Christmas season often marked the grimmest point for early American settlements, particularly the Jamestown Colony in Virginia. The winter of 1609-1610 is known simply as the “Starving Time.” Out of approximately 500 settlers, only about 60 survived.

The mystery that still haunts historians today is not that they starved, but the extreme and desperate measures that were taken. Archaeological evidence has confirmed that the settlers resorted to cannibalism during that brutal winter.

The unsolved element centers on the “lost” history of what occurred between Thanksgiving and Christmas Day. Historical records from the survivors are sparse. Who was targeted? Were certain groups preyed upon? Was it a systemized, desperate attempt to survive, or random acts of violence? We will probably never know for sure.

The Hessdalen Lights

The Hessdalen Lights happen year-round, but winter is peak season. Especially around December, when the valley turns into a frozen, white bowl under the relentless polar night. That’s when locals see glowing orbs, pulsing lights, and massive fireballs that float, zig-zag, and hover for minutes at a time.

Scientists have been actively studying this area since the 1980s, ruling out aircraft, satellites, car lights, drones, and atmospheric reflections. The lights simply refuse to conform to any conventional explanation. The best theory involves some kind of weird, self-igniting ionized plasma created by metallic dust in the valley. The issue? No one can reproduce it in a lab.

The Phantom Ship of the Carolinas Coastline

Every winter, typically between mid-December and New Year’s, people along the Outer Banks of North Carolina and down the coast report seeing the phantom masts of a burning ship drifting just offshore. Locals have many names for it—the Carroll A. Deering (a historical ghost ship), or “The Ship of the Lost Colony.” The story goes back at least to the 1700s.

Is it connected to the vanished Roanoke colonists? Is it a doomed pirate crew reliving its final moments? The strange part is the seasonal consistency. It’s an unexplained, recurring visual phenomenon. It only appears when the winter fog, atmospheric conditions, and low sun angle combine just right.

The 1909 Christmas Day Electrical Blackout

In a major historical head-scratcher, on Christmas Day in 1909, numerous electrical grids across the American Northeast suffered unexplained and simultaneous failures. What makes it a mystery is that the technology of the time—early, less interconnected electrical systems—shouldn’t have failed in such a coordinated way.

Initial theories blamed poor maintenance or overloaded holiday circuits. Yet no single cause could be isolated across different cities using different power generation methods. Some blamed atmospheric electricity, others a strange, unseen terrestrial current. It was a failure of technology and infrastructure that simply didn’t make sense for the era. The event sparked serious, long-term scientific investigations into power distribution stability. However, ultimately, no single culprit was ever officially and definitively named.

The Debate Over the Star of Bethlehem

We all know the story of the star that guided the Magi. What most people don’t realize is that astronomers—actual, modern scientists—still argue over what this could have been, if it was a real celestial object at all. Was it an incredibly rare planetary alignment? A massive supernova? A highly visible comet? The frustrating part is that every astronomical explanation works… and also doesn’t work. For example:

• Comets were considered bad omens and would have been extensively recorded by meticulous Chinese astronomers (they weren’t).
• A Supernova would have left a remnant cloud we could spot today (we can’t find one that fits the date).
• The Planetary Alignment theory (a series of unique, close conjunctions of Jupiter and Saturn) fits the timeline, but it doesn’t match the brightness or directional “moving” nature described in the ancient texts.

Two thousand years later, we are no closer to an answer. Every December, astronomers dust off the mystery again because it’s genuinely one of the most frustrating, detailed, and confusing events in early recorded history.

Winter Solstice Rituals and Their Persistence

The Christmas season is fundamentally a rebranding of the pagan Winter Solstice (Yule, Saturnalia, etc.), and the ultimate mystery is how deeply those ancient, non-Christian rituals are still baked into our modern holiday.

Why do we bring evergreen trees indoors? Why is the mistletoe considered sacred? And why do we burn a Yule Log? These are all practices tied directly to pagan rituals meant to sustain life and ward off the darkness during the longest night of the year. The true mystery is how the Church successfully repurposed and weaved these deep-seated pagan acts of superstition into a totally new, centralized holiday?
