As reported in last week's Lunar and Planetary Science Conference in Houston, two most promising candidates for stardust have been identified. They were collected during NASA´s Stardust mission that probed the interstellar stream during 15 months. Since 2006 not only scientists but also amateurs worldwide are scanning samples for the proverbial needle in the haystack: dust particles from others parts of our galaxy that were carried to our solar system via the interstellar...

NASA scientists said they might have identified the first specks of interstellar dust in materials collected by the agency's Stardust spacecraft. The interstellar dust is comprised of tiny particles that take part in making stars and planets. The Stardust spacecraft's primary job was to catch dust streaming from Comet Wild 2 and return it to Earth for analysis. However, scientists also hoped to collect particles of interstellar dust. The material was collected in a 2.9 billion mile...

Though comets are thought to be some of the oldest, most primitive bodies in the solar system, new research on comet Wild 2 indicates that inner solar system material was transported to the comet-forming region at least 1.7 million years after the formation of the oldest solar system solids. The research by Lawrence Livermore National Laboratory scientists and colleagues provides the first constraint on the age of cometary material from a known comet. The findings were published in the Feb....

Just three days shy of one year before its planned flyby of comet Tempel 1, NASA's Stardust spacecraft has successfully performed a maneuver to adjust the time of its encounter by eight hours and 20 minutes. The delay maximizes the probability of the spacecraft capturing high-resolution images of the desired surface features of the 2.99-kilometer-wide (1.86 mile) potato-shaped mass of ice and dust. With the spacecraft on the opposite side of the solar system and beyond the orbit of Mars, the...

DENVER, Feb. 18 /PRNewswire/ -- NASA's Stardust-NExT (New Exploration of Tempel) spacecraft fired its engines for 22 minutes 53 seconds on Feb. 17 to purposely delay its arrival at comet Tempel 1 by 8 hours 21 minutes. In one year, the Lockheed Martin- (NYSE: LMT) built spacecraft will still fly by the comet on Feb. 14, 2011, Valentines' Day, but the encounter time will now be 8:42 p.m. PT. The low-cost Discovery Program Mission of Opportunity will expand the investigation of comet...

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...

GREENBELT, Md., Aug. 17 /PRNewswire-USNewswire/ -- NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO ) "Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet," said Dr. Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. "Our discovery...

U.S. space agency scientists say they've found glycine, a basic building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet, said Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. Our discovery supports the theory that some of life's ingredients formed in space and were delivered to Earth long ago by meteorite...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...
