Stardust's payload holds first potential interstellar space particles

A team of scientists has been combing through the payload of NASA’s Stardust spacecraft since it returned to Earth in 2006. They found seven rare, microscopic interstellar dust particles, that most likely came from outside of our solar system. If confirmed, these particles would be the first samples of contemporary interstellar dust. Scientists caution that additional tests must be done before they can say definitively that these are pieces of debris from interstellar space. But if they are, the particles could help explain the origin and evolution of interstellar dust.The research report appears in the August 15 issue of the journal Science. Twelve other papers about the particles will appear next week in the journal Meteoritics & Planetary Science.Michael… »
