That quest by Russian, British and American scientific teams for water samples is the topic of an article in the current edition of Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society (ACS), the world's largest scientific society. http://phys.org/news249740172.html Space & Earth Wed, 29 Feb 2012 12:16:22 EST news249740172 An international team of scientists has demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology. http://phys.org/news247837619.html Physics Tue, 07 Feb 2012 11:47:15 EST news247837619 Two Australian adventurers have made Antarctic history by becoming the first team to travel unaided to the South Pole and back, surviving three months of "extreme hardship", they said on Friday. http://phys.org/news246860823.html Space & Earth Fri, 27 Jan 2012 04:27:28 EST news246860823 Extraordinarily cold temperatures in the winter of 2010/2011 caused the most massive destruction of the ozone layer above the Arctic so far: The mechanisms leading to the first ozone hole above the North Pole were studied by scientists of the KIT Institute of Meteorology and Climate Research (IMK). According to these studies, further cooling of the ozone layer may enhance the influence of ozone-destroying substances, e.g. chlorofluorocarbons (CFC), such that repeated occurrence of an ozone hole above the Arctic has to be expected. http://phys.org/news246197253.html Space & Earth Thu, 19 Jan 2012 12:08:00 EST news246197253 (PhysOrg.com) -- While the rest of the world gets on with meeting the New Year head on, two research scientists from New Zealand are traveling to the Antarctic to take measurements of the magnet South Pole. Such periodic measurements are necessary geo-scientists say, because the magnetic poles keep moving around. The south magnetic pole, for example is slowly moving north toward Australia at almost ten miles per year; this matters because very accurate ground measurements are necessary to keep satellites properly calibrated, ensuring such things as GPS coordinates are accurate. http://phys.org/news244724131.html Space & Earth Mon, 02 Jan 2012 10:55:49 EST news244724131 Scientists have been puzzled by periodic bursts of radiation, known as the Saturn kilometric radiation (SKR), that occur in the planet's magnetosphere. These emissions occur at a rate that is close to, but not quite the same as, the rate at which the planet rotates. http://phys.org/news244531799.html Space & Earth Sat, 31 Dec 2011 05:30:06 EST news244531799 (PhysOrg.com) -- NASA's Gravity Recovery And Interior Laboratory (GRAIL)-A spacecraft is within 24 hours of its insertion burn that will place it into lunar orbit. At the time the spacecraft crossed the milestone at 1:21 p.m. PST today (4:21 p.m. EST), the spacecraft was 30,758 miles (49,500 kilometers) from the moon. http://phys.org/news244531382.html Space & Earth Sat, 31 Dec 2011 05:23:23 EST news244531382 (PhysOrg.com) -- This view from NASA's Cassini spacecraft looks toward the south polar region of Saturn's largest moon, Titan, and shows a depression within the moon's orange and blue haze layers near the south pole. http://phys.org/news244360291.html Space & Earth Thu, 29 Dec 2011 06:20:02 EST news244360291 After sinking Norway's plans to repatriate explorer Roald Amundsen's three-mast ship Maud from the Arctic, Canada signalled Monday it may buy the shipwreck. http://phys.org/news243579383.html Space & Earth Tue, 20 Dec 2011 04:56:29 EST news243579383 A century ago, two groups of explorers crossed the Antarctic continent, competing for the distinction of being the first to stand at the geographic South Pole. Norwegian native Roald Amundsen and his men won that race. His British rival, Robert Falcon Scott, and his party arrived roughly a month later, only to perish on the way back to their base camp. http://phys.org/news243156801.html Space & Earth Thu, 15 Dec 2011 07:33:53 EST news243156801 One hundred years ago Norwegian explorer Roald Amundsen won the race to the South Pole in a dramatic and ultimately fatal duel with British adventurer Robert Scott that captured the world's attention. http://phys.org/news243058151.html Space & Earth Wed, 14 Dec 2011 04:20:01 EST news243058151 (PhysOrg.com) -- Next week marks 100 years since Roald Amundsen reached the South Pole. As a team of scientists brave the Antarctic to validate data from ESA’s CryoSat mission, it’s hard to imagine what these first intrepid explorers would have thought of today’s advances in polar science. http://phys.org/news242897798.html Space & Earth Mon, 12 Dec 2011 07:36:49 EST news242897798 Norwegian Prime Minister Jens Stoltenberg will join dozens of adventurers at the South Pole this week to mark the 100th anniversary of countryman Roald Amundsen's groundbreaking expedition to the frozen continent. http://phys.org/news242885555.html Space & Earth Mon, 12 Dec 2011 04:50:01 EST news242885555 The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on September 12, stretching 10.05 million square miles, the ninth largest on record. Above the South Pole, the ozone hole reached its deepest point of the season on October 9 when total ozone readings dropped to 102 Dobson units, tied for the 10th lowest in the 26-year record. http://phys.org/news238338421.html Space & Earth Thu, 20 Oct 2011 14:07:15 EST news238338421 A US scientist stranded in Antarctica for almost two months following a suspected stroke has been evacuated from the South Pole to New Zealand in a hazardous airlift. http://phys.org/news238124199.html Space & Earth Tue, 18 Oct 2011 02:36:46 EST news238124199 (PhysOrg.com) -- A new image from NASA's Dawn spacecraft shows a mountain three times as high as Mt. Everest, amidst the topography in the south polar region of the giant asteroid Vesta. http://phys.org/news237525502.html Space & Earth Tue, 11 Oct 2011 04:19:00 EST news237525502 Two Australian adventurers who made history by kayaking unassisted to New Zealand set off on Monday hoping to bag a new record by walking from the Antarctic coast to the South Pole and back. http://phys.org/news236834141.html Space & Earth Mon, 03 Oct 2011 04:15:56 EST news236834141 (PhysOrg.com) -- Dawn took this image during its current orbit of Vesta, traveling from the day side to the night side. http://phys.org/news230533075.html Space & Earth Fri, 22 Jul 2011 05:58:07 EST news230533075 (PhysOrg.com) -- Scientists working with NASA's Dawn spacecraft have created a new video showing the giant asteroid Vesta as the spacecraft approaches this unexplored world in the main asteroid belt. http://phys.org/news227185778.html Space & Earth Mon, 13 Jun 2011 12:09:56 EST news227185778 (PhysOrg.com) -- ESA's Mars Express celebrates eight years in space with a new view of ice in the southern polar region of Mars. The poles are closely linked to the planet’s climate and constantly change with the seasons. Their study is an important scientific objective of the mission. http://phys.org/news226749351.html Space & Earth Wed, 08 Jun 2011 10:56:12 EST news226749351 For the first time, scientists have an almost complete sky map of high-energy cosmic rays. http://phys.org/news223614848.html Physics Tue, 03 May 2011 04:14:26 EST news223614848 In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator. While previous work has shown that the ozone hole is changing the atmospheric flow in the high latitudes, the Columbia Engineering paper, "Impact of Polar Ozone Depletion on Subtropical Precipitation," demonstrates that the ozone hole is able to influence the tropical circulation and increase rainfall at low latitudes in the Southern Hemisphere. This is the first time that ozone depletion, an upper atmospheric phenomenon confined to the polar regions, has been linked to climate change from the Pole to the equator. http://phys.org/news222613588.html Space & Earth Thu, 21 Apr 2011 14:06:45 EST news222613588 (PhysOrg.com) -- Physicist Nathan Whitehorn and a team of researchers with the IceCube collaboration have failed to come up with evidence to prove that neutrinos come from, or are caused by, gamma ray bursts, (cosmic explosions) after a year of study. http://phys.org/news222084262.html Physics Fri, 15 Apr 2011 11:40:01 EST news222084262 (PhysOrg.com) -- Galaxies often occur in groups. Our own Milky Way galaxy, for example, and its local neighborhood with about fifty galaxies are at the edge of the Virgo Cluster, a collection of somewhere between 1200 and 2000 galaxies. Galaxy clusters are the most massive objects in the universe, and their formation is thought to have begun from small spatial variations in the density of matter in the early universe. Clusters are therefore powerful probes of the growth of structure in the early universe, and their numbers and masses help astronomers test cosmological models including galaxy formation. http://phys.org/news221718346.html Space & Earth Mon, 11 Apr 2011 05:26:55 EST news221718346
