Once you download it, you become part of the worldwide effort to detect signals from aliens. The universe is so vast they re guessing we aren t the only intelligent life around. But they want proof. To look for alien intelligence, the scientists at SETI are using radio telescopes to search the sky. Their giant telescopes are monitoring radio signals that might be sent by intelligent life elsewhere in the universe.
Radio waves are very powerful and travel great distances through the universe.
Even if extraterrestrials don't send a message directly to us, we may still detect their radio signals. After all, the biggest radio telescope in the world is on the job. It would take 10 billion bowls of cereal to fill the radio dish to the brim. It's impossible for scientists to keep up with all the incoming radio telescope data. The folks at SETI need your help .
