5/26/2016: SETI Gets an UpgradePrint Post
Dan Werthimer doesn’t mean to be rude, but he’s getting ready to eavesdrop on the neighbors.
For decades, astronomers have been listening for messages sent to us—a “Hello, is anyone out there?” signal from intelligent aliens. But now Werthimer is about to get nosier; his team at the University of California at Berkeley is conducting the first search for communities on other worlds that are speaking to one another—between planets and even across star systems. And to do it, he has two of the world’s largest radio telescopes and support from a planet‑hunting optical telescope.
Thanks to a new initiative announced last July, Werthimer’s team will begin searching for extraterrestrial civilizations, using instruments with greater sensitivity and scanning across a wider range of frequencies than any SETI (search for extraterrestrial intelligence) project to date. Called Breakthrough Listen, it began earlier this year and will continue for a decade at a price tag of $100 million. “It’s a lot of money, a lot of telescope time,” says Werthimer. “We’ll be able to look at a hundred billion radio channels simultaneously. A big problem in SETI is we don’t know on what frequency ET might be transmitting, so the more channels you can listen to, the better chance you have of finding” a communication.
