That project is the Prebiotic Interstellar Molecule Survey (PRIMOS). Launched in 2004, it plans to inventory all of the chemicals found in space. In the past, scientists would decide on the molecule they were looking for, and then set their telescope's radio frequency to that one molecule. The approach paid off, netting a number of aldehydes and simple sugars, but Anthony Remijan of the National Radio Astronomy Observatory in Green Bank, West Virginia, thought there was a better way. Why not, he and colleagues reasoned, look at all frequencies available to us instead and see what comes up?
PRIMOS has gathered so much data, in fact, that it now needs volunteers to sift through it all. Interested? You can use the Java application on its Web site to bring up all of the reduced and averaged radio-frequency data, or if you really want to get crazy, you can bring it up in raw format. Search for features that could be from new molecules, and voilà, you could discover your own chemical. There's a complete database of spectral frequencies for all of the known molecules to help you out.
