In summer 2025, a roughly 4.56-billion-year-old meteorite crashed through the roof of a home in McDonough, Georgia — and analysis by researchers at the University of Georgia determined the rock is approximately 20 million years older than Earth itself, meaning the homeowner spent that night sleeping in a house that had just been physically struck by a piece of the solar system older than the planet she was standing on

Mars has been surprising scientists for decades with traces of its ancient geological past. But now researchers have stumbled upon a discovery that no one has ever seen on the Red Planet before. They have discovered a completely new type of rock and mineral in a fragment of a Martian meteorite that could change our understanding of how the planet evolved billions of years ago.

The fireball was visible in broad daylight. Roughly 200 witnesses across Georgia and South Carolina saw it streak across the sky that afternoon, bright enough that more than 160 of them reported it to the American Meteor Society within a few hours, and bright enough to be picked up by an orbiting satellite. The object, by NASA’s initial estimate, had been roughly three feet in diameter and weighed over 2,000 pounds when it hit the upper atmosphe…
