Scientists have found some of the most primitive matter containing abundant interstellar material analyzed to date amongst dust particles collected from the upper atmosphere by NASA aircraft. The samples were gathered in April 2003 during the Earth's passage through the dust stream left behind by comet 26P/Grigg-Skjellerup.
