Antarctica is Earth's southernmost continent, containing the geographic South Pole. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it is the fifth-largest continent and the coldest, driest, and windiest of all continents.
Antarctica has no permanent residents, but a number of government-maintained research stations support a rotating population of scientists and staff. The continent is governed by the Antarctic Treaty System, which preserves it for peaceful scientific research and suspends territorial sovereignty claims.
Antarctica plays a critical role in Earth's climate system and contains about 70% of the world's freshwater in the form of ice.

March of the Penguins (French: La Marche de l'empereur; French pronunciation: [la maʁʃ də lɑ̃ˈpʁœʁ]) is a 2005 French nature documentary film directed and written by Luc Jacquet. The documentary depicts the yearly journey of the emperor penguins of Antarctica. In autumn, all the penguins of breeding age (five years old and over) leave the ocean, which is their normal habitat, to walk inland to their ancestral breeding grounds. There, the penguins participate in a courtship that, if successful, results in the hatching of a chick. For the chick to survive, both parents must make multiple arduous journeys between the ocean and the breeding grounds over the ensuing months. (Full article...)

The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD. (Full article...)

The climate of Antarctica is the coldest and driest on Earth. Antarctica averages 166 mm (6.5 in) of precipitation per year and snow rarely melts on most parts of the continent. After Antarctic snow becomes compressed, it becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the continent, because of the katabatic winds. Most of Antarctica has an ice-cap climate (Köppen classification EF) with very cold and dry weather. (Full article...)

Geography of Antarctica |

The Transantarctic Mountains (abbreviated TAM) comprise a mountain range of uplifted rock (primarily sedimentary) in Antarctica which extends, with some interruptions, across the continent from Cape Adare in northern Victoria Land to Coats Land. These mountains divide East and West Antarctica. They include a number of separately named mountain groups, which are often again subdivided into smaller ranges. (Full article...)

The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and lives exclusively in Antarctica. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb). Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. (Full article...)
