Way back in 2006, a group of scientists inflated a giant balloon intended to float over Antarctica. Kitted out with sophisticated equipment, the inflatable was launched in order to detect high-energy particles arriving on Earth from space. While it was in the air, though, the balloon observed something peculiar. And now the scientific consensus of the past century or so is being called into question.
Antarctica – the most southerly continent on planet Earth – was initially sighted in 1820 by a Russian naval expedition. The first landing on Antarctica, however, is not thought to have taken place until January 1895, when a pair of Norwegian adventurers finally arrived at Cape Adare, to the north of the continent.
