Scientists may have discovered the world's largest canyon, buried under a vast Antarctic ice sheet. Antarctica's ice sheet is the largest single mass of ice found anywhere on Earth, but it is full of mysteries. 

Half of the Antarctic ice sheet is more than three miles from any bed topography measurement, and major data gaps exist in several parts of this frigid continent. There is now a detailed map of Antarctica's peaks and valleys, with more being discovered every day.
