That dinosaur-killing asteroid also triggered massive magma releases beneath the ocean, study finds

For decades, researchers have pointed to a cataclysmic asteroid smashing into the planet as the reason the dinosaurs, and many other species of life on Earth, were wiped out during what's formally known as the Cretaceous-Paleogene extinction event (named for the periods that came before and followed after it). That impact, which scientists think left the roughly 110-mile-wide Chicxulub crater in the Gulf of Mexico, would have vaporized living things nearby and sent choking clouds of debris into the air, obscuring the sun.
