'Dusters' Look For Interstellar Dust Tracks
When science gets too big, it's time to either automate or call in volunteers. Sometimes, you have to do both.
Pieces of aerogel on NASA's Stardust spacecraft not only picked up samples of comet Wild 2, they also captured, separately, particles of interstellar dust on a side of the collector not exposed to the comet. The comet particles are easily detectable, but scientists estimate that the interstellar dust collector may have nabbed only a dozen . . .
