(PhysOrg.com) -- Scientists once thought that life could originate only within a solar system's "habitable zone," where a planet would be neither too hot nor too cold for liquid water to exist on its surface. But according to planetary scientist Francis Nimmo, evidence from recent NASA missions suggests that conditions necessary for life may exist on the icy satellites of Saturn and Jupiter. http://www.physorg.com/news180112635.html Space & Earth Tue, 15 Dec 2009 18:55:19 EST news180112635 Scientists who study the melting of Greenland's glaciers are discovering that water flowing beneath the ice plays a much more complex role than they previously imagined. http://www.physorg.com/news180116235.html Space & Earth Tue, 15 Dec 2009 17:20:12 EST news180116235 Extensive analyses and modeling of Cassini imaging and heat-mapping data have confirmed and extended previous ideas that migrating ice, triggered by infalling reddish dust that darkens and warms the surface, may explain the mysterious two-toned "yin-yang" appearance of Saturn's moon Iapetus. The results, published online Dec. 10 in a pair of papers in the journal Science, provide what may be the most plausible explanation to date for the moon's bizarre appearance, which has puzzled astronomers for more than 300 years. http://www.physorg.com/news179677088.html Space & Earth Thu, 10 Dec 2009 14:18:55 EST news179677088 (PhysOrg.com) -- Preventing the havoc wrought when freezing rain collects on roads, power lines, and aircrafts could be only a few nanometers away. A University of Pittsburgh-led team demonstrates in the Nov. 3 edition of Langmuir a nanoparticle-based coating developed in the lab of Di Gao, a chemical and petroleum engineering professor in Pitt's Swanson School of Engineering, that thwarts the buildup of ice on solid surfaces and can be easily applied. http://www.physorg.com/news176044143.html Chemistry Thu, 29 Oct 2009 14:09:54 EST news176044143 (PhysOrg.com) -- Intrigued by NASA lunar missions in the 1990s which suggested the existence of ice within craters at the moon's poles, NASA scientist Dr. Edwin Ethridge and his team started cooking up a way to extract water from lunar soil. http://www.physorg.com/news175198787.html Space & Earth Mon, 19 Oct 2009 19:21:54 EST news175198787 NASA is figuring out how to make water from moondust. Sounds like magic? "No magic--" says Ed Ethridge of NASA's Marshall Space Flight Center "-- just microwaves. We're showing how microwaves can extract water from moondust by heating it from the inside out." http://www.physorg.com/news174241668.html Space & Earth Thu, 08 Oct 2009 17:30:02 EST news174241668 The recent discovery of plumes containing water vapor erupting from the south pole of the frigid Saturnian moon Enceladus set off a firestorm of debate. http://www.physorg.com/news174236314.html Space & Earth Thu, 08 Oct 2009 15:59:48 EST news174236314 (PhysOrg.com) -- Astronomers at the some of the best ground-based telescopes in southern Arizona plan to observe two lunar impacts at 4:30 a.m. and 4:34 a.m. Arizona time Friday. http://www.physorg.com/news174146100.html Space & Earth Wed, 07 Oct 2009 14:58:52 EST news174146100 (PhysOrg.com) -- Scientists are seeing sub-surface water ice that may be 99 percent pure halfway between the north pole and the equator on Mars, thanks to quick-turnaround observations from orbit of fresh meteorite impact craters on the planet. http://www.physorg.com/news173021371.html Space & Earth Thu, 24 Sep 2009 15:00:02 EST news173021371 A new study has revealed the origins of tiger stripes and a subsurface ocean on Enceladus- one of Saturn's many moons. These geological features are believed to be the result of the moon's unusual chemical composition and not a hot core, shedding light on the evolution of planets and guiding future space exploration. http://www.physorg.com/news166874016.html Space & Earth Wed, 15 Jul 2009 10:54:50 EST news166874016 Mars gets as far as 250 million miles away, but many parts of it closely resemble places on Earth, including its landscape, history of water, soil and even its weather, says a Texas A&M University researcher in the current issue of "Science" magazine. http://www.physorg.com/news165763556.html Space & Earth Thu, 02 Jul 2009 15:10:01 EST news165763556 (PhysOrg.com) -- Below 0 °C, water turns to ice. But beyond that, or below about -75 °C, the ice may turn back into liquid water. While scientists have previously predicted this phase transition with computer simulations, recent experiments may have finally demonstrated the existence of this ultra-cold water. http://www.physorg.com/news165084657.html Chemistry Wed, 24 Jun 2009 17:51:25 EST news165084657 (PhysOrg.com) -- NASA's Lunar Crater Observation and Sensing Satellite, known as LCROSS, is enroute from Northrop Grumman's facility in Redondo Beach, Calif., to NASA's Kennedy Space Center in Florida in preparation for a spring launch. http://www.physorg.com/news154117276.html Space & Earth Tue, 17 Feb 2009 18:22:16 EST news154117276 University of Arkansas researchers have used chemistry and geology to create a model that may explain the mystery of how modern-day gullies form on the surface of Mars. http://www.physorg.com/news153416239.html Space & Earth Mon, 09 Feb 2009 15:37:58 EST news153416239 (PhysOrg.com) -- Astronomers will use the powerful University of Arizona/Smithsonian MMT Observatory on Mount Hopkins, Ariz., to search for lunar water ice when NASA fires a 2-ton rocket into a polar crater on the moon later this year. http://www.physorg.com/news153152542.html Space & Earth Fri, 06 Feb 2009 14:23:50 EST news153152542 Scientists have discovered where they believe would be the best place to find ice on the moon. http://www.physorg.com/news148805928.html Space & Earth Thu, 18 Dec 2008 06:58:48 EST news148805928 Vast Martian glaciers of water ice under protective blankets of rocky debris persist today at much lower latitudes than any ice previously identified on Mars, says new research using ground-penetrating radar on NASA's Mars Reconnaissance Orbiter. http://www.physorg.com/news146409495.html Space & Earth Thu, 20 Nov 2008 13:18:15 EST news146409495 (PhysOrg.com) -- By confining water in nano-sized spaces, physicists from Leiden University in the Netherlands have turned water into ice at room temperature.
