Summary[edit]
DescriptionSouth Pole-banner1.jpg |
English: South Pole banner; 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. There is a background of green light. This is the Aurora Australis, which dances thorugh the sky virtually all the time during the long Antarctic night (winter).The photo's surreal appearance makes the station look like a futuristic Mars Station. |
