It represents the most pristine sample of > minerals from outer space. Samples of the meteorite, totalling 850 > grams, were collected from Tagish Lake and purchased in 2006 by a > research consortium that included the University of Alberta. > > "We are lucky that the meteorite was untouched by humans hands, > avoiding contamination by organic compounds that we have on our > fingers," said Herd. "This meteorite can tell us new information about > the birth and evolution of our solar system, and the very fact that > it's been kept frozen, essentially pristine, uncontaminated by human > hands, gives us an unprecedented opportunity to explore new scientific > avenues that were heretofore impossible. > > "We can do things with this meteorite that nobody's ever done before." > > > > -- > ......................................................... > Michael Gilmer (Louisiana, USA) > Member of the Meteoritical Society. > Member of the Bayou Region Stargazers Network. > Websites - http://www.galactic-stone.com and http://www.glassthrower.com > .......................................................... > ______________________________________________ > http://www.meteoritecentral.com > Meteorite-list mailing list > Meteorite-list at meteoritecentral.com > http://six.pairlist.net/mailman/listinfo/meteorite-list Received on Tue 30 Jun 2009 03:54:52 PM PDT |
