BERKELEY, Calif., Aug. 15 (UPI) -- As it's name suggests, NASA's Stardust probe had one primary mission when it was launched in 1999 -- capture space dust, both from a comet's coma and free-floating particles from the surrounding cosmos. It accomplished that task and safely parachuted back to Earth in 2006.
Now, after several years of lab work with the particles, scientists say Stardust likely captured interstellar particles -- dust from outside our solar system.
