Dust samples collected by high-flying aircraft in the upper atmosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. The stratospheric dust includes minute grains that likely formed inside stars that lived and died long before the birth of our sun, as well as material from molecular clouds in interstellar space. This "ultra-primitive" material likely wafted into the atmosphere after the Earth passed through the trail of an Earth-crossing comet in 2003, giving scientists a rare opportunity to study cometary dust in the laboratory. http://www.physorg.com/news176400764.html Space & Earth Mon, 02 Nov 2009 17:00:02 EST news176400764 (PhysOrg.com) -- NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. http://www.physorg.com/news169736472.html Space & Earth Mon, 17 Aug 2009 14:01:57 EST news169736472 (PhysOrg.com) -- Saturday, Feb. 7, marked the 10th anniversary of the launch of NASA's well-traveled Stardust spacecraft. http://www.physorg.com/news153417966.html Space & Earth Mon, 09 Feb 2009 16:10:24 EST news153417966 (PhysOrg.com) -- Having returned the world's first particles from a comet, NASA's Stardust sample return capsule will join the collection of flight icons in the Smithsonian's National Air and Space Museum in Washington.
