Aurora Australis blankets the sky overhead of the 10-meter South Pole Telescope at Amundsen-Scott South Pole Station, Antarctica. Like its more familiar counterpart, the Aurora Borealis, or Northern Lights, the Aurora Australis is caused by the solar wind passing through the upper atmosphere. But the Aurora Australis is much less frequently observed because so few people live in Antarctica during the austral winter. Photo #1 by Keith Vanderlinde, National Science Foundation
