The University of California at Berkeley has created SETI@home, an Internet volunteer project that uses home computers to listen for narrow-bandwidth radio signals from extra terrestrial intelligence. Our computer processors can analyze the perpetual flow of data from the Arecibo radio telescope in Puerto Rico while the easily downloadable software runs as a screensaver.
Instead of staring at your cat bouncing all over the screen, you can embark on a search for alien civilizations. With over 5 million volunteers worldwide, SETI@home is currently the world’s largest distributed computing effort. SETI@home uses BOINC software, which also allows volunteers to process data from some of the largest experiments in the world, ranging from biomedical research searching for cures, astrophysics research at CERN to cryptography, mathematical and environmental research.
