Summary
Description Amundsen-Scott marsstation ray h.jpg |
English:
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
.

Vue de la station américaine
Amundsen-Scott
au pôle sud, éclairée par la pleine lune, durant la longue nuit polaire. La nouvelle station est visible tout à gauche, la centrale électrique au centre, et l'ancien atelier de mécanique en bas à droite. Durant la nuit polaire, seule la lumière rouge est utilisée pour limiter la pollution lumineuse et ne pas perturber les expériences d'astrophysique menées dans la base. La lumière verte est due aux
aurores australes
qui sont quasi-permanentes durant la nuit polaire. L'apparence surréaliste de la photo fait penser à une base futuriste sur Mars.
