The $100 million, 10-year project, called Breakthrough Listen, will examine 100 galaxies and 1 million stars for evidence of alien technology. The Green Bank Telescope in West Virginia and the Parkes Telescope in Australia will scan for radio pings from other planets, and the Automated Planet Finder in Mount Hamilton, Calif., will search for extraterrestrial lasers. All data will be public, whether they reveal aliens or just silence.
Opponents say we shouldn’t waste money looking for beings that might not exist, and instead focus on surefire science and projects that help humans. But past SETI projects haven’t searched extensively (cosmically speaking) due to financial restraints and the hugeness of the universe.
As SETI pioneer Jill Tarter likes to say, so far SETI has scooped a single glass of water from the cosmic ocean, and no one would conclude the earthly sea is fishless from a 1-cup sample. Breakthrough Listen, if nothing else, will fill more cups.
