South Pole Telescope at Night

May 1, 2012
The 10-meter South Pole Telescope and the BICEP (Background Imaging of Cosmic Extragalactic Polarization) Telescope at Amundsen-Scott South Pole Station, against the night sky with the Milky Way. The red lights are used to minimize light pollution, but still enable people to see while walking to and from the facility during the six months of darkness. Both of these telescopes collect data on cosmic microwave background radiation and black matter. 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). Credit: Keith Vanderlinde, National Science Foundation
