Antarctica looks amazing from space—but this video shows that its gnarled canyons and caves look equally impressive close-up, too.

Shot in Antarctica last November by Enrico Sacchetti from a drone helicopter for the Italian Science Foundation to document its research, the video shows the rugged surface of ice, shaped and distorted by glacial activity and extreme weather. It looks sensational—but it's quite nice to watch it from the comfort of a warm armchair. [Enrico Sacchetti]
