A massive new telescope will soon begin scanning the skies for laser flashes from extraterrestrials. Researchers are focusing on laser light because they think advanced intelligent beings would use it to communicate with us, rather than the far more primitive radio signal (related: “Alien Contact More Likely by ‘Mail’ Than Radio, Study Says” ). “Pulse lasers allow the sending of very bright light very far, very quickly,” said Bruce Betts. Betts is a planetary scientist and director of programs at the Pasadena, California-based Planetary Society, which funded the new telescope.
