The sea ice cover of the Southern Ocean reached its yearly maximum extent on Oct. 6.

The recent announcement of evidence of flowing, liquid water just below the Martian surface made headlines across the globe.

This modified container in Antarctica is part of the Franco-Italian Concordia research station and is used to store snow samples.

Concordia research station in Antarctica is a place of extremes. In winter no sunlight is seen for four months and the typical crew of twelve live in complete isolation.

Wind-swept mountain peaks peek above the ice of Dronning Maud Land in Antarctica, as seen by ESA's Proba-1 microsatellite, whose two-year design life has been extended by 11 years and counting.

A recent acceleration in ice loss in a previously stable region of Antarctica has been detected by ESA's ice mission.

Modeling Antarctic Ocean Currents

The oceans play an important role in the earth's climate; they transport heat from equator to pole, provide moisture for rain, and absorb carbon dioxide from the atmosphere.

A new NASA study finds the last remaining section of Antarctica's Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and likely to disintegrate completely before the end of the decade.

Astronomers building an Earth-size virtual telescope capable of photographing the event horizon of the black hole at the center of our Milky Way have extended their instrument to the bottom of the Earth -- the South Pole -- thanks to recent efforts by a team led by Dan Marrone of the University of Arizona.

The Italian French Concordia research station in Antarctica sits in the largest desert in the world.

New Threat to East Antarctic Ice

Researchers have discovered two seafloor troughs that could allow warm ocean water to reach the base of Totten Glacier, East Antarctica's largest and most rapidly thinning glacier.

Scientific Spring in Isolated Antarctica

In Antarctica, the crew of the FrenchItalian Concordia research station are preparing for the winter. They have to survive six months of complete isolation four in darkness because the Sun never rises above the horizon while they perform science in one of the most barren places on Earth.

Along a 900-kilometer (560-mile) stretch of Antarctica's Pacific Coast, 18 major volcanoes jut from the ice sheet.

Looking Under Antarctic Ice

This image shows a slice through almost 3 kilometers (1.9 miles) of ice spanning a few hundred kilometers on each side of the South Pole

Four bleary-eyed men wearing grease-smeared tan jackets or red parkas emerge from what first appears to be a leftover prop from a Mad Max film. Nine silver smokestacks tower above nine fire-engine-red hot water tanks, all bolted down to a large sled.

West Antarctic Melt Rate Has Tripled

A comprehensive, 21-year analysis of the fastest-melting region of Antarctica has found that the melt rate of glaciers there has tripled during the last decade.

In May 2014, two new studies concluded that a section of the land-based West Antarctic ice sheet had reached a point of inevitable collapse.

Pollution Beat Explorers to South Pole

Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December 1911. More than 100 years later, an international team of scientists that includes a NASA researcher has proven that air pollution from industrial activities arrived to the planet's southern pole long before any human.

A new study by researchers at NASA and the University of California, Irvine, finds a rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline, with nothing to stop the glaciers in this area from melting into the sea.
