A full moon and 25 second exposure allowed sufficient light into this photo

June 8, 2010
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. 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. The photo's surreal appearance makes the station look like a futuristic Mars Station. (Date of Image: July 2005)
