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

History

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

  • Heavy Cosmic Rays - Part I: The Flight of...
    on September 14, 2020 at 12:12 pm

    In December 2019, SuperTIGER clawed its way back into the upper atmosphere. The second flight of the SuperTIGER cosmic ray experiment, officially dubbed SuperTIGER-II, flew high above the icy continent for more than a month, collecting data on the high-energy particles that zip through the cosmos.

  • Detecting Anomalous Life Swarms
    on September 1, 2020 at 12:12 pm

    The seas around Antarctica are alive, but that life is not evenly distributed everywhere. Vast regions of barren ocean are punctuated by oases of concentrated nutrients that create hotspots of biological activity.

  • Chasing Aerosol Ghosts
    on July 28, 2020 at 12:12 pm

    For a big mass of air, the Earth's upper atmosphere is a complicated place. The changing seasons cause temperatures and pressures to rise and fall, altering the characteristics of the planet's atmospheric layers, sometimes dramatically.

  • Where the Ice Layers Grow
    on July 13, 2020 at 12:12 pm

    Hunting for the perfect patch of ice can be a herculean task. Knut Christianson, of the University of Washington, spent three weeks with his research team in a barren and remote part of Antarctica, scouring the landscape for the perfect spot.

    Scientists are taking a close look at Antarctica's largest land animal. It's a small insect called the Antarctic midge, and they don't grow much bigger than a fingernail.
