British adventurer Henry Worsley has died from exhaustion and dehydration after nearly completing his goal of crossing the Antarctic unaided. The former army officer was on a charity mission trying to be the first to cross the Antarctic without any support and was inspired by polar explorer Sir Ernest Shackleton’s unfinished crossing of a hundred years earlier.
A canyon system potentially bigger than the Grand Canyon in the U.S. could be hiding beneath the Antarctic ice sheet, measuring 1,000km long and as much as 1km deep. Researchers from Durham University and Imperial College London – along with American, Australian, Indian, and Chinese scientists studying satellite data, think that a massive canyon system could be hidden underneath a largely unexplored region of the Antarctic, called Princess Elizabeth Land. The study is being verified by a geological survey, which is now under way.
