Two Explorers Descend Into An Active Volcano, and Live to Tell About It

Discover reports on the unlikely adventure of explorers and daredevils Sam Cossman and George Kourounis, who (with caution employed at least in their choice of gear) "rappelled down the crater inside Mount Marum, which is situated on one of 80 islands that make up the Pacific Republic of Vanautu. And they’ve just uploaded video of this up-close encounter with one of the world’s most volcanically active locations." Warning: the linked video may inspire envy and wanderlust, even if it doesn't expose any deep new science.
