A free download program that runs while you're in screensaver mode. What it does is download data packets that have been collected by radio telescopes and will analyze the spectrum. Why it does this is to look for the possibility of a signal from intelligent life out there. Why is this important?

And while the odds of finding anything out there are difficult to calculate (since we really don't know all the variables out there) the impact that actually learning that we aren't alone would be profound. This is a simple way to contribute, requires no money, requires no effort, it simply requires that you leave your computer on once in a while when you're not using it and allow it to help the human race learn something. read more
