The interstellar dust particles returned to Earth by the Stardust mission are the first such pristine dust particles ever collected in space, and scientists are eager to "get their hands" on them. We estimate that Stardust collected less than 100 interstellar dust particles. They are tiny-only about a micron (a millionth of a meter) in size! These miniscule particles are embedded in anollector 1,000 square centimeters in size. Finding them will be like searching for a handful of ants on a football field while searching one 5 cm x 5 cm square at a time.
This is where you come in:
By asking for help from talented volunteers like you from all over the world, we can do this project in months instead of years. To find the tiny particles we are using an automated scanning microscope to automatically collect digital images of the entire Stardust interstellar collector. We call these "stacks" of images. All in all, there will be nearly a million of them. These are available to Stardust@home volunteers around the world. You can view them with the aid of a special Virtual Microscope ( ).
Together, you and thousands of other Stardust@home participants will find the first pristine interstellar dust particles ever brought to Earth!
The discoverer of an interstellar dust particle will appear as a co-author on scientific papers by the Stardust@home collaboration announcing the discovery of the particle. The discoverer will also have the privilege of naming the particle!
How to participate:
First, you will go through a short web-based tutorial. Then, you must pass a web-based test to qualify to register and participate. After passing the test and registering, you will be able to login to the VM. The VM will automatically connect to our server and download focus movies. The VM will work within your web browser, under your control.
The VM downloads and displays focus movies, so that you can do just what someone sitting at a real microscope would do: focus up and down in each movie to look for particle tracks. To use the VM you will need a relatively fast internet connection, and the latest version of just about any web browser.

The best attitude for this project is this: Have Fun!
As with any research project, the outcome is uncertain. This is a new approach to doing research. We are in utterly new territory. Please be patient, and remember that the most important thing is to have fun.
The search will take several years to complete. Don't be discouraged if you don't find something right away, or even later in the project if many interstellar dust grains have already been found. The last particle found may be the most interesting.
We will rely on your feedback to improve things as we go. If you have ideas, suggestions, or questions, please use ourto communicate those to us.
