The Geographic South Pole is marked by the stake on the right NASA image showing Antarctica and the South Pole in 2005. The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's axis of rotation meets its surface.
Polar night is a phenomenon that occurs in the northernmost and southernmost regions of Earth when the Sun remains below the horizon for more than 24 hours. This only occurs inside the polar circles. [1] The opposite phenomenon, polar day or midnight sun, occurs when the Sun remains above the horizon for more than 24 hours.
At Earth's poles the Sun appears at the horizon only and all day around equinox, marking the change between the half year long polar night and polar day.The picture shows the South Pole right before March equinox, with the Sun appearing through refraction despite being still below the horizon.
Chart of the southern constellations from declination –40° to the south celestial pole by the Jesuit missionary François Noël published in Acta Eruditorum, 1711.. From the South Pole, in good visibility conditions, the Southern Sky features over 2,000 fixed stars that are easily visible to the naked eye, while about 20,000 to 40,000 with the aided eye.
The Amundsen-Scott South Pole Station is named after Roald Amundsen - the Norwegian explorer who led the first expedition to the South Pole - and also Robert Scott, the UK explorer whom Amundsen ...
The South Pole is the other point where Earth's axis of rotation intersects its surface, in Antarctica. Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars . Earth's rotation is slowing slightly with time; thus, a day was shorter in the past.
Aurora australis appearing in the night sky of Swifts Creek, 100 km (62 mi) north of Lakes Entrance, Victoria, Australia. In the Southern Hemisphere, the Sun passes from east to west through the north, although north of the Tropic of Capricorn the mean Sun can be directly overhead or due south at midday. The Sun follows a right-to-left ...
At the top of the world in the middle of the Arctic Ocean lies the geographic North Pole, the point where all the lines of longitude that curve around Earth from top to bottom converge in the north.
