3D images confirm ancient asteroid crater beneath Atlantic
Researchers have unveiled high-resolution 3D images of the Nadir Crater, a 9 km-wide impact site hidden 300 meters below the Atlantic seafloor. Formed 66 million years ago by an asteroid strike, the crater coincides with the dinosaur-extinction event linked to the Chicxulub impact. The data reveals details of the immediate aftermath, including massive tsunamis and liquefied sediments.
