On January 1, 1995, a laser beneath a North Sea platform measured a wave 25.6 meters tall — roughly the height of an eight-storey building.

For centuries, sailors had reported isolated walls of water far larger than the seas around them. Oceanographers had good mathematical reasons to doubt those stories. Then the Draupner platform recorded one. This episode follows the measurement that changed ocean science, the evidence that rogue waves are far more common than once thought, and the competing explanations for how they form.

The general mechanism is becoming clearer. Exactly how the Draupner wave formed is still debated.

Reality Is Strange — real phenomena, verified, and stranger than they should be.

In June 2019, NASA's Curiosity rover measured the highest concentration of methane it had ever detected on Mars. Days later, it was gone.

Curiosity has been finding traces of methane in Gale Crater for more than a decade. But the Trace Gas Orbiter — an instrument far more sensitive and built specifically to detect gases like methane — has never found it. The contradiction has survived years of investigation, and recent research has raised an uncomfortable possibility: the methane may be coming from Mars, disappearing through chemistry we don't understand, or partly coming from Curiosity itself.

As of 2026, there is still no consensus explanation.

Reality Is Strange — real phenomena, verified, and stranger than they should be.

In 1993, a listening system on the floor of the North Pacific recorded a whale calling at 51.75 hertz — a voice unlike any known whale in the region.

For more than a decade, researchers followed that voice across thousands of kilometres of ocean without ever seeing the animal that made it. It became known as the loneliest whale in the world. But the recordings never actually proved it was lonely — and the strongest explanations point somewhere stranger.

No one has ever matched the original call to a living animal.
