Ancient asteroid craters may have sparked Earth’s oxygen-producing life
A recent discovery in South Korea suggests that ancient asteroid impacts may have played a crucial role in the development of oxygen-producing life on Earth. Researchers found stromatolites, which are layered structures formed by ancient microbes, within the Hapcheon impact crater. This evidence indicates that asteroid strikes could have created warm, mineral-rich lakes that fostered early microbial life, potentially contributing to the Great Oxidation Event.
- ▪Scientists discovered stromatolites inside the Hapcheon impact crater in South Korea.
- ▪The stromatolites likely formed in a hydrothermal lake created by an asteroid impact.
- ▪This discovery may provide insights into the Great Oxidation Event and the conditions that allowed early life to thrive.

Opening excerpt (first ~120 words) tap to expand
Science News from research organizations Ancient asteroid craters may have sparked Earth’s oxygen-producing life Asteroid impacts may have helped kickstart oxygen-producing life on Earth. Date: May 22, 2026 Source: National Research Council of Science & Technology Summary: A hidden crater in South Korea may hold clues to one of the biggest turning points in Earth’s history: the rise of oxygen. Scientists discovered fossil-like stromatolites — layered structures built by ancient microbes — inside the Hapcheon impact crater, suggesting that asteroid strikes may have created warm, mineral-rich lakes where early oxygen-producing life could flourish.
