Hidden 5-mile wide asteroid crater beneath the Atlantic revealed in stunning 3D

A massive crater hidden beneath the Atlantic seafloor has been confirmed as the result of an asteroid strike from 66 million years ago. The new 3D seismic data reveals astonishing details about the violent minutes following impact—towering tsunamis, liquefied rock, and shifting seabeds. Researchers call it a once-in-a-lifetime look at how oceanic impacts unfold.
