Antarctica : continent around the South Pole; a plateau covered by a great ice cap and mountain peaks area about 5,500,000 square miles (14,300,000 square kilometers) — Webster
Antarctica is Earth’s southernmost continent. It contains the geographic South Pole and is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra. — Wikipedia
Although myths and speculation about a Terra Australis (“Southern Land”) date back to antiquity, the first confirmed sighting of the continent is commonly accepted to have occurred in 1820 by the Russian expedition of Fabian Gottlieb von Bellingshausen and Mikhail Lazarev. The continent, however, remained largely neglected for the rest of the 19th century because of its hostile environment, lack of resources, and isolation. — Wikipedia

High above the surface of the Earth, flow giant, invisible clouds of charged gas that can degrade radio transmissions, disrupt GPS Signals and play havoc with other communications and navigation systems. But they're not always showing up when scientists predicted. This year geophysicist Alex […]
The Flight of X-Calibur

Antarctica can be a double-edged sword for astronomers: conditions there are some of the best in the world for observing the heavens, but the harshness of the place can be hard on equipment. In December 2018, astronomers who launched the x-ray telescope "X-Calibur" to study neutron stars and black […]

Rocks are cracking up all over Antarctica's McMurdo Dry Valleys. Though it may take hundreds of thousands, or even millions of years, the slow but inevitable processes of weathering eventually reduce all rocks into sand or even clay.
Digging For Fishies

The mountains of Antarctica may seem an unlikely place to find fish, but they were exactly what a team of paleontologists working along the edge of the Polar Plateau last winter were looking for. In a region now defined by dry rocky terrain poking up through vast sheets of thick ice, the […]
Icefin Tests the Waters

Navigating a robot through the frozen ocean's frigid waters was all in a day's work for the RISE UP science team. From their makeshift mission control in a small fish hut, the researchers maneuvered their underwater vehicle through the seawater below.
