I know this is a long read, but check it out and then pre-register here.

Finding the incredibly tiny interstellar dust impacts in the Stardust Interstellar Dust Collector (SIDC) will be extremely difficult. Because dust detectors on the Ulysses and Galileo spacecraft have detected interstellar dust streaming into the solar system, we know there should be about 45 interstellar dust impacts in the SIDC. These impacts can only be found using a high-magnification microscope with a field of view smaller than a grain of salt. But the aerogel collector that we have to search enormous by comparison, about a tenth of a square meter (about a square foot) in size. The job is roughly equivalent to searching for 45 ants in an entire football field, one 5cm by 5cm (2 inch by 2 inch) square at a time! More than 1.6 million individual fields of view will have to searched to find the interstellar dust grains. We estimate that it would take more than twenty years of continuous scanning for us to search the entire collector by ourselves.

The only way that we can think of to find these exciting interstellar dust grains is to recruit talented volunteers to help us search. First, you will go through a web-based training session. This is not for everyone: you must pass a test to qualify to register to participate. After passing the test and registering, you will be able to download a virtual microscope (VM). The VM will automatically connect to our server and download so-called "focus movies" -- stacks of images that we will collect from the Stardust Interstellar Dust Collector using an automated microscope at the Cosmic Dust Lab at Johnson Space Center. The VM will work on your computer, under your control. You will search each field for interstellar dust impacts by focusing up and down with a focus control.

The more focus movies you examine, the better the chances are that you'll find an interstellar dust grain. But we have no minimum expectation -- you should search through focus movies as long as you're having fun doing it. Just remember that you are looking at the first collector that has gone into deep space and come back. This is a very special opportunity!

The Stardust@home website will include a list of top participants.

In recognition of the critical importance of the Stardust@home volunteers, the discoverer of an interstellar dust particle will appear as a co-author on any scientific paper by the Stardust@home collaboration announcing the discovery of the particle.
