Amundsen–Scott South Pole Station

The original Amundsen–Scott Station was built by Navy Seabees for the federal government of the United States during November 1956, as part of its commitment to the scientific goals of the International Geophysical Year, an effort lasting from January 1957 to June 1958 to study, among other things, the geophysics of the polar regions of Earth.
Before November 1956, there was no permanent artificial structure at the pole, and practically no human presence in the interior of Antarctica. The few scientific stations in Antarctica were near its coast. The station has been continuously occupied since it was built and has been rebuilt, expanded, and upgraded several times.
The station is the only inhabited place on the surface of the Earth from which the Sun is continuously visible for six months; it is then continuously dark for the next six months, with approximately two days of averaged dark and light, twilight, namely the equinoxes. These are, in observational terms, called one extremely long "day" and one equally long "night". During the six-month "day", the angle of elevation of the Sun above the horizon varies incrementally. The Sun reaches a rising position throughout the September equinox, and then it is apparent highest at the December solstice which is summer solstice for the south, setting on the March equinox.
During the six-month polar night, air temperatures can drop below and blizzards are more frequent. Between these storms, and regardless of the weather for wavelengths unaffected by drifting snow, the roughly months of ample darkness and dry atmosphere make the station an excellent site for astronomical observations.
The number of scientific researchers and members of the support staff housed at the Amundsen–Scott Station has always varied seasonally, with a peak population of around 150 in the summer operational season from October to February. In recent years the wintertime population has been around 50 people. Provided by Wikipedia
