NASA is about to bring some stardust back to earth. A spacecraft is capturing samples of solar wind, which carries electrically charged particles that were blown out of the sun. It never occurred to me before that stardust exists in the real world, and not just in fairytales and Disney movies. This part of the article talks about what the scientists are going to do with the stardust:
Opening the capsule in a modern clean room should allow an analysis with an accuracy unparalleled by efforts from the 1969-72 Apollo missions, says team scientist Don Burnett of the California Institute of Technology.Since I still kind of think of stardust as something magical, I keep thinking they're studying it to figure out why it has special powers. But that's probably not the case.
