Seti@home is one chance to find out if people exist somewhere besides earth. Seti@home might be able to detect radiowaves above all the crashing and banging that's going on in the universe (not to mention my back yard).
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
