Southern lights for Antarctica Day © Stuart Holroyd/Alamy
In honor of Antarctica Day, you"re seeing the southern lights dazzle above Halley VI, the latest version of the six-decade-old Halley Research Station in the British Antarctic Territory. The modular building stands on hydraulic legs and is movable via retractable skis. The five previous facilities, Halley I–V, were each compromised by Antarctica"s harsh climate and decommissioned. Since 2017, when scientists discovered dangerous cracks in the surrounding Brunt Ice Shelf, Halley has been unmanned during the dark Antarctic winter months—but the research team equipped it with an autonomous micro-turbine that keeps its atmospheric instruments ticking as the snowdrifts pile up.
