I'm sure a lot of people here are familiar with the recent return of NASA's StarDust spacecraft from its voyage to collect particals from a comet. The goal of the mission was to study the space particals (which are literally the building blocks of the universe) in hopes of unlocking the universes secrets.
However, there are so many of these tiny particals to look through, that NASA needs our help in order to look through all of them in a resonable time. Clicking the link at the bottom of this post will bring you to the official StarDust website where you can register and receive images of these particals once NASA officially starts the research. You must look through these images and find a piece of interstellar dust. As an incentive, NASA will let you name the any piece of interstellar dust that you find
Please help NASA.
