(Phys.org) —An ice cloud taking shape over Titan's south pole is the latest sign that the change of seasons is setting off a cascade of radical changes in the atmosphere of Saturn's largest moon. Made from an unknown ice, this type of cloud has long hung over Titan's north pole, where it is now fading, according to observations made by the Composite Infrared Spectrometer (CIRS) on NASA's Cassini spacecraft. http://phys.org/news284911027.html Space & Earth Thu, 11 Apr 2013 14:57:16 EST news284911027 Millions of people in northern Europe are still battling snow and ice, wondering why they are being punished with bitter cold when—officially—spring has arrived and Earth is in the grip of global warming. http://phys.org/news283665855.html Space & Earth Thu, 28 Mar 2013 05:04:22 EST news283665855 (Phys.org)—Late Friday, Feb. 2, an overcast day in St. Louis, the twitter feed for the Super-TIGER cosmic ray experiment burst into life, as the Super-TIGER team received word that NASA's Columbia Scientific Balloon Facility, which provides operations support for scientific ballooning in Antarctica, had decided to terminate the flight of the balloon carrying their detector aloft in the polar vortex. http://phys.org/news279550444.html Space & Earth Fri, 08 Feb 2013 12:55:15 EST news279550444 (Phys.org)—Before he left for Antarctica in November, W. Robert Binns, principal investigator for Super-TIGER, said that he would be deliriously happy if the balloon carrying the cosmic-ray detector stayed up 30 days. http://phys.org/news278151293.html Space & Earth Wed, 23 Jan 2013 08:15:06 EST news278151293 (Phys.org)—It's November 30 and a scattering of people in St. Louis, Missouri, Pasadena, California, and Greenbelt, Maryland, are getting antsy, clicking repeatedly on http://www.csbf.nasa.gov/antarctica/ice.htm to see whether anything is up yet. http://phys.org/news273745709.html Space & Earth Mon, 03 Dec 2012 08:40:10 EST news273745709 With wild storms and a vast ring system, nothing seems small around Saturn. But as NASA's Cassini spacecraft loops high over Saturn's poles, scientists are taking time to explore the little things including a swirling vortex, the miniature moon Mimas, and another tiny ovoid moon named Methone. http://phys.org/news272015786.html Space & Earth Tue, 13 Nov 2012 09:00:11 EST news272015786 A University of Utah study suggests something amazing: Periodic changes in winds 15 to 30 miles high in the stratosphere influence the seas by striking a vulnerable "Achilles heel" in the North Atlantic and changing mile-deep ocean circulation patterns, which in turn affect Earth's climate. http://phys.org/news267600423.html Space & Earth Sun, 23 Sep 2012 13:00:21 EST news267600423 (Phys.org)—Posing for portraits for NASA's Cassini spacecraft, Saturn and its largest moon, Titan, show spectacular colors in a quartet of images being released today. One image captures the changing hues of Saturn's northern and southern hemispheres as they pass from one season to the next. http://phys.org/news265538873.html Space & Earth Thu, 30 Aug 2012 10:00:01 EST news265538873 (Phys.org) -- The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect leading to increased odds of severe winter weather outbreaks in the Northern Hemisphere's middle latitudes -- think the "Snowmageddon" storm that hamstrung Washington, D.C., during February 2010. http://phys.org/news258179454.html Space & Earth Wed, 06 Jun 2012 05:31:43 EST news258179454 For the first half of this year's winter, the big news was warm temperatures and lack of snow. Ski resorts were covered in bare dirt, while January temperatures in southern California topped July highs. http://phys.org/news248690178.html Space & Earth Fri, 17 Feb 2012 08:36:34 EST news248690178 (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 Geophysical phenomena such as the dynamics of the atmosphere and ocean circulation are typically modeled mathematically by tracking the motion of air or water particles. These mathematical models define velocity fields that, given (i) a position in three-dimensional space and (ii) a time instant, provide a speed and direction for a particle at that position and time instant. http://phys.org/news210938773.html Physics Tue, 07 Dec 2010 10:06:25 EST news210938773 The 2008 ozone hole – a thinning in the ozone layer over Antarctica – is larger both in size and ozone loss than 2007 but is not as large as 2006. http://phys.org/news142595756.html Space & Earth Tue, 07 Oct 2008 10:55:56 EST news142595756
