Berkeley SETI Research Center conducts experiments searching for electromagnetic signatures of intelligent extraterrestrial civilizations, spanning wavelengths from radio to visible light. We're the creators of the SETI@home volunteer computing software, that utilizes spare resources on volunteer computers to aid in processing data from radio telescopes. And we're excited to be participating in the new Breakthrough Listen initiative to use the Green Bank, Parkes, and Automated Planet Finder telescopes to dramatically expand the search for cosmic company.
