World's Oldest Known Impact Crater Discovered in Western Australia
- Australian scientists have discovered the world’s oldest known meteorite-impact crater, which could reshape understanding of the origins of life and Earth itself, according to a study from Curtin University.
- The crater, created by an impact 3.5 billion years ago, provides new insights into early Earth's crust formation, according to researchers from Curtin University.
- Before this discovery, the oldest impact crater was 2.2 billion years old, according to Professor Tim Johnson, co-lead of the study.
- Professor Chris Kirkland noted that this impact could explain how life began by creating environments suitable for microbial life.

"We were at the center of one of the oldest meteorite craters ever discovered on Earth"
Researchers found in Australia the largest crater caused by a meteorite. Dated about 3.3 billion years ago, it could profoundly alter our understanding of the origins of life on the planet.
2.75 Billion-Year-Old Rocks Rewrite the Story of Earth’s Early Life
A study of ancient stromatolites reveals that ammonium reservoirs in early Earth’s oceans, likely influenced by volcanic activity, may have supported microbial life before the Great Oxidation Event. Analysis of fossilized stromatolites dating back more than 2.5 billion years has shed new light on Earth’s environmental conditions before the emergence of oxygen. A research team [...]
