(Inhabitat) A giant hole the size of Maine or Lake Superior has suddenly appeared on the surface of Antarctica and scientists are not quite sure how it came into being. “It looks like you just punched a hole in the ice,” said atmospheric physicist Kent Moore, a professor at the University of Toronto’s Mississauga campus. The sudden emergence of this hole, for the second year in a row, has confounded scientists, whose access to the site is limited. “This is hundreds of kilometers from the ice edge,” said Moore. “If we didn’t have a satellite, we wouldn’t know it was there.”
