The Scar Under Mexico
A 10-kilometer asteroid slammed into Earth just over 66 million years ago and left a crater buried under Mexico’s Yucatán Peninsula. That hidden scar, Chicxulub, is about 200 kilometers wide and is linked to the extinction that wiped out 75% of species, including all non-avian dinosaurs.Chicxulub Crater and the Asteroid That Ended Dinosaurs

The Day Earth Changed
The Chicxulub impact unleashed winds over 1,000 kilometers per hour, carved a cavity about 100 kilometers wide and 30 kilometers deep, and triggered megatsunamis over 100 meters tall. Some simulations suggest the first waves may have soared to 1.5 kilometers high.Chicxulub Crater and the Asteroid That Ended Dinosaurs
