SETI—the Search for Extraterrestrial Intelligence—has been one of the most captivating areas of science since its inception in 1960, when the astronomer Frank Drake used an 85-foot radio telescope in the first-ever attempt to detect interstellar radio transmissions sent by beings outside our solar system. Yet despite its high public visibility and near-ubiquity in blockbuster Hollywood science fiction, throughout most of its 55-year history SETI has languished on the fringes of scientific research, garnering relatively scant funding and only small amounts of dedicated observation time on world-class telescopes.
