Understanding the dynamics and chemistry that create planetary systems can help astronomers in their search for Earth-like planets in the galaxy. http://www.physorg.com/news175444213.html Space & Earth Thu, 22 Oct 2009 15:40:01 EST news175444213 According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin. http://www.physorg.com/news175092150.html Space & Earth Sun, 18 Oct 2009 13:45:26 EST news175092150 When Tony Garchinski heard a loud crash just after 9 p.m. on Friday, September 25 he didn't think much of it. That is, until he awoke the next morning to find the windshield of his mom's Nissan Pathfinder with a huge crack in it. Making note of the 'unusual' rocks he later found on the car's hood, Garchinski chalked the incident up to vandalism and filed a police report. http://www.physorg.com/news174925756.html Space & Earth Fri, 16 Oct 2009 15:30:09 EST news174925756 (PhysOrg.com) -- Tiny microscopic creatures commonly known as water bears (also called Tardigrades), along with a few other life forms, will be sent to the Martian moon Phobos to test whether organisms can survive for long periods of time in deep space. The mission, called the Living Interplanetary Flight Experiment (LIFE), was originally going to be launched earlier this month, but it has been delayed due to safety and technical issues. Currently, the scientists hope to launch the specimens on the Russian Phobos-Grunt spacecraft in 2011, the next time that the orbits of Earth and Mars offer a launch window. http://www.physorg.com/news174659888.html Space & Earth Tue, 13 Oct 2009 13:39:08 EST news174659888 (PhysOrg.com) -- Astronomers from The University of Western Ontario in London, Canada have released footage of a meteor that was approximately 100 times brighter than a full moon. The meteor lit up the skies of southern Ontario two weeks ago and Western astronomers are now hoping to enlist the help of local residents in recovering one or more possible meteorites that may have crashed in the area of Grimsby, Ontario. http://www.physorg.com/news174133342.html Space & Earth Wed, 07 Oct 2009 11:22:47 EST news174133342 (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 Molecules vital to life have been detected in outer space and isolated in meteorites and comets. Some of this material that rained down on Earth may have jump-started biology. If so, these space seeds also may have planted a particular molecular orientation, or "handedness," that spread to the world's first creatures. New research is studying how this handedness could arise in space. http://www.physorg.com/news172502439.html Space & Earth Fri, 18 Sep 2009 14:30:01 EST news172502439 (PhysOrg.com) -- Toward the end of September, the sun will turn a spotlight on the asteroid Juno, giving that bulky lump of rock a rare featured cameo in the night sky. Those who get out to a dark, unpolluted sky will be able to spot the asteroid's silvery glint near the planet Uranus with a pair of binoculars. http://www.physorg.com/news172417127.html Space & Earth Thu, 17 Sep 2009 14:39:21 EST news172417127 (PhysOrg.com) -- Researchers have discovered an unusual kind of meteorite in the Western Australian desert and have uncovered where in the Solar System it came from, in a very rare finding published today in the journal Science. http://www.physorg.com/news172415123.html Space & Earth Thu, 17 Sep 2009 14:09:32 EST news172415123 Argentina can lay claim to the world's largest crater field, a volcanic area in Patagonia known as the "Devil's Slope," according to a study released Tuesday. http://www.physorg.com/news171643252.html Space & Earth Tue, 08 Sep 2009 16:30:03 EST news171643252 (PhysOrg.com) -- NASA's Mars Rover Opportunity is investigating a metallic meteorite the size of a large watermelon that is providing researchers more details about the Red Planet's environmental history. http://www.physorg.com/news169145414.html Space & Earth Mon, 10 Aug 2009 17:50:41 EST news169145414 (PhysOrg.com) -- Composition measurements by NASA's Mars Exploration Rover Opportunity confirm that this rock on the Martian surface is an iron-nickel meteorite. http://www.physorg.com/news168801850.html Space & Earth Thu, 06 Aug 2009 18:24:44 EST news168801850 (PhysOrg.com) -- The Opportunity rover has eyed an odd-shaped, dark rock, about 0.6 meters (2 feet) across on the surface of Mars, which may be a meteorite. http://www.physorg.com/news168534413.html Space & Earth Mon, 03 Aug 2009 16:30:02 EST news168534413 (PhysOrg.com) -- A research program aimed at using platinum as an exploration guide for nickel has for the first time been able to put a time scale on the planet`s large-scale convection processes. http://www.physorg.com/news168184418.html Space & Earth Thu, 30 Jul 2009 15:50:01 EST news168184418 (PhysOrg.com) -- An analysis of Martian meteorites has led scientists to believe that Mars was molten for up to 100 million years after it formed, thwarting the evolution of early life on the planet. http://www.physorg.com/news167407498.html Space & Earth Tue, 21 Jul 2009 15:05:57 EST news167407498 The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team of colleagues. http://www.physorg.com/news164304081.html Space & Earth Mon, 15 Jun 2009 18:50:01 EST news164304081 (PhysOrg.com) -- Formic acid, a compound implicated in the origins of life, has been found at record levels on a meteorite that fell onto a frozen Canadian lake in 2000. http://www.physorg.com/news163259938.html Space & Earth Wed, 03 Jun 2009 15:00:34 EST news163259938 (PhysOrg.com) -- Large bombardments of meteorites approximately four billion years ago could have helped to make the early Earth and Mars more habitable for life by modifying their atmospheres, suggests the results of a paper published today in the journal Geochimica et Cosmochima Acta. http://www.physorg.com/news163071856.html Space & Earth Mon, 01 Jun 2009 10:44:47 EST news163071856 Dinosaurs were dying out much earlier than the mass extinction event 65 million years ago, Natural History Museum scientists report in the Proceedings of the Royal Society journal today. http://www.physorg.com/news160324445.html Other Sciences Thu, 30 Apr 2009 15:34:45 EST news160324445 Comets have always fascinated us.

Does this same soup exist on planets around other stars? A new study from NASA's Spitzer Space Telescope hints that planets around stars cooler than our sun might possess a different mix of potentially life-forming, or "prebiotic," chemicals. http://www.physorg.com/news158341061.html Space & Earth Tue, 07 Apr 2009 16:38:41 EST news158341061 (PhysOrg.com) -- Just before dawn on Oct. 7, 2008, an SUV-sized asteroid entered Earth's atmosphere and exploded harmlessly over the Nubian Desert of northern Sudan. Scientists expected the asteroid, called 2008 TC3, had blown to dust in the resulting high-altitude fireball. http://www.physorg.com/news157740396.html Space & Earth Tue, 31 Mar 2009 17:47:00 EST news157740396 (PhysOrg.com) -- The car-sized asteroid that exploded above the Nubian Desert last October was small compared to the dinosaur-killing, civilization-ending objects that still orbit the sun. But that didn't stop it from having a huge impact among scientists. This was the first instance of an asteroid spotted in space before falling to Earth. Researchers rushed to collect the resulting meteorite debris, and a new paper in Nature reports on this first-ever opportunity to calibrate telescopic observations of a known asteroid with laboratory analyses of its fragments. http://www.physorg.com/news157211890.html Space & Earth Wed, 25 Mar 2009 14:58:46 EST news157211890 (PhysOrg.com) -- NASA scientists analyzing the dust of meteorites have discovered new clues to a long-standing mystery about how life works on its most basic, molecular level. http://www.physorg.com/news156523757.html Chemistry Tue, 17 Mar 2009 15:50:05 EST news156523757 First an explosion as powerful as thousands of megatons of TNT rained meteorites down on North America.
