National Geographic reports that a vast network of rivers and lakes exists under the Anarctic ice cap.

This watery environment may be more than one-and-a-half times the size of the United States, scientists say, which would make it the world's largest wetland.

"This is essentially a whole new world that ten years ago we didn't know existed," said Michael Studinger, a geophysicist at the Lamont-Doherty Earth Observatory of Columbia University in New York.
