Some 66 million years after the Chicxulub asteroid impact kickstarted the Cretaceous–Paleogene (K-T) extinction, scientists are still finding stunning evidence of its destruction. In 2021, researchers ...

On Saturday (June 29), an asteroid larger than the Great Pyramid of Giza will fly past Earth at about three-quarters the distance from Earth to the moon. The asteroid, named 2024 MK, poses no risk to ...
