The moon is the greatest enigma in the cosmos. It's just slightly smaller than Jupiter's largest moon, Titan, yet the Earth is 50X smaller than Jupiter.
The moon is essential for complex life to have evolved, yet we really don't know where it came from.
Thoughts about SETI and SETI@home
I run SETI on my computer because I am tickled that I can be a part of this Grand project.
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.
