Aurora Over South Pole Telescope

November 16, 2012
Aurora australis ("southern lights") blankets the sky overhead of the 10-meter South Pole Telescope at Amundsen-Scott South Pole Station, Antarctica. The telescope collects data on cosmic microwave background radiation and black matter. 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 on Antarctica during the austral winter. Amundsen-Scott South Pole Station is one of three U.S. research stations on the Antarctic continent. All of the stations are operated by the National Science Foundation's U.S. Antarctic Program (USAP). Further information about USAP is available Here.
