A full moon and 25 second exposure allowed sufficient light into this photo taken at Amundsen-Scott South Pole Station during the long Antarctic night in July of 2005. The new station can be seen at far left, power plant in the center and the old mechanic's garage in the lower right. Red lights are used outside during the winter darkness as their spectrum does not pollute the sky, allowing scientists to conduct astrophysical studies without artificial light interference. The green light in the sky is the aurora australis. (Chris Danals/National Science Foundation)

A cable portrudes from the ice wall at Explorer's Cover, New Harbor, McMurdo Sound in this photo taken on November 12, 2005. The cable was used for the Remotely Operable Micro-Environmental Observatory (ROMEO), an underwater camera. Connected to onshore equipment and linked by radio to the Internet, ROMEO allowed scientists to study benthic fauna year-round. (Steve Clabuesch/National Science Foundation)
