Oldest Asteroid Crater Found

Scientists have just uncovered Earth’s oldest known asteroid impact crater, dating back 3 billion years in Western Australia’s remote outback. Using super-durable minerals zircon and apatite, researchers confirmed the crater’s age through unique branching patterns in zircon caused by the impact’s heat, with apatite providing crucial cross-verification. This discovery is groundbreaking — it’s the only known crater from the Archean eon, when continents were forming, and likely struck ancient ocean waters teeming with early life like stromatolites. Though the asteroid’s size and crater’s final dimensions remain unknown, the find offers a rare, clear window into how our planet’s surface was shaped billions of years ago.
