A huge crater has been discovered under a layer of ice in Antarctica.
A massive crater, 480 kilometers in diameter, has been discovered beneath Antarctica's eastern Arctic ice sheet, which may be the remains of a meteorite impact 250 million years ago. Scientists, using data from NASA satellites, suggest that this event may have contributed to the "great extinction," during which 95% of marine and 70% of land life on Earth disappeared. Professor Ralph Von Frese of Ohio State University emphasizes that the impact may have had a greater impact than that which led to the extinction of the dinosaurs. An international team of scientists from the US, Russia, and Korea is investigating this phenomenon. A 480-kilometer-wide crater (satellite image below) has been discovered beneath the eastern Arctic ice sheet. Scientists say this discovery could be the mark of the first massive meteorite impact 250 million years ago. The Wilkes Land singularity was discovered using NASA satellites to map subtle differences in Earth's weight. "The Wilkes L...
