Is there life out there? Well lets hope so, it's an awful waste of space if there isn't any. Running Seti@home was just something fun. If I can help by giving redundant CPU time it's a small price to pay.
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.
