PARIS, July 2 (UPI) -- A European satellite has spotted a vast crater in Antarctica's icy surface scientists say they think was formed when a lake under miles of ice suddenly drained.
Combining new measurements from the European Space Agency's CryoSat spacecraft with older data from NASA's ICESat satellite, researchers have mapped the large crater left behind by the lake, and even determined the scale of the flood that formed it, an ESA release reported Tuesday.
