If you think back, you’ll recall that some scientists were trying to bring back space dust collected by a probe. Well, they’ve taken lots of pictures of the aerogel they were collecting the dust in and now everyone can get involved helping them find dust particles. If you visit the Stardust@home website, you too can participate! Unlike SETI@home, Stardust@home has people actually looking at pictures rather than running a screensaver that crunches numbers when you’re not otherwise using your computer. There’s more information on the Planetary Society’s website, too.
It just launched yesterday, and it appears that their servers are a tad overloaded right now, so I haven’t been able to get into the website to register and try looking for space dust, yet.
