Why do I run SETI@home? I find the software & methodology quite fascinating.
Should we earthlings transmit a beacon? With the millions of signals transmitted every day, I think we are.
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.
