Chicxulub Asteroid Impact Site Remained Hot for Millions of Years, Supporting Microbial Life
The Chicxulub asteroid, which struck Earth 66 million years ago, created a massive impact site in what is now Mexico. This event is known for causing the extinction of the dinosaurs and a nuclear winter that lasted at least 15 years. Recent studies have revealed that the impact site remained hot for at least 8 million years, much longer than previously thought. This prolonged heat created a hydrothermal system, a network of hot water-filled pockets within the melted rock, which provided a habitat for microbial life. Researchers drilled into the crater to study rock cores, finding evidence of ongoing hydrothermal activity and microbial life for millions of years after the impact.
