Dinosaur-killing asteroid impact site stayed hot for millions of years

The asteroid strike that wiped out the dinosaurs hit with such force that it took at least 8 million years for the impact site to cool down, creating a warm underground ecosystem where microscopic life thrived. The Chicxulub asteroid, which collided with Earth 66 million years ago at what is now Mexico, is thought to have been as large as 15 kilometres in diameter. The strike caused so much climate chaos that it wiped out three-quarters of species on Earth.

The asteroid that wiped out the dinosaurs may have created a vast underground habitat for life that lasted 8 million years

The asteroid that wiped out the dinosaurs may have created a vast underground habitat for life that lasted 8 million years The Chicxulub impact may have actually helped nurture life while destroying it, too. The asteroid impact that doomed the dinosaurs may also have built one of Earth's longest-lasting underground ecosystems. When a roughly 6-mile-wide (10-kilometer-wide) asteroid slammed into what is now Mexico's Yucatán Peninsula 66 million years ago, it triggered a global catastrophe...
