Russian Billionaire Will Spend $100 Million To Hunt For Aliens

Russian billionaire, Yuri Milner who made his name through savvy investments in social media companies (like Facebook) is now the theoretical-physicist-turned-tech-tycoon is sinking $100 million into science’s most quixotic quest: the search for extraterrestrial intelligence.

We should be asking the difficult questions,” says Milner, echoing President John F. Kennedy’s famous words about going to the moon.

The scientific braintrust will have the best technology, a $100 million can buy.

It’s a dream come true,” said Andrew Siemion, director of the Berkeley SETI Research Center and another leader on the initiative.

The key purchase will be thousands of hours per year of observation time on two of the world’s most powerful radio telescopes, the Green Bank Telescope in West Virginia and the Parkes Telescope in New South Wales, Australia. (A specialized optical telescope at the Lick Observatory in California is also involved.) Together, the radio telescopes will cover 10 times more sky than previous searches and scan the entire 1-to-10 gHz range, the so-called “quiet zone” in the spectrum where radio waves are unobscured by cosmic sources or Earth’s atmosphere; presumably, intelligent aliens will know to broadcast in this zone if they want anyone to hear them.

So that’s where the second big purchase will come in. The Breakthrough Listen researchers will need specialized electronics to process all the data; a room at University of California’s Campbell Hall is already set aside for a team to create the hardware and software to make the search possible. All these ideas have been out there in the SETI community for decades, says Siemion. “We just haven’t had the computing technology and the resources,” he says. Milner’s gift changes that playing field.

Eventually, the researchers will make all the data public, so anyone can join the search for intelligent life. Breakthrough Listen will also be part of SETI@home, in which people contribute spare cycles from their home computers to parse SETI data via a screensaver.

Why spend the money now?

Milner says he was compelled by the fact that planets orbiting their stars in the so-called habitable zone—where the temperature makes it possible for liquid water to exist—are more common than anyone thought, as shown by results from NASA’s Kepler mission.

“For the first time, we have scientific evidence of how many places can harbor life.”

 

The number of habitable planets is a variable in the Drake equation, and Kepler’s results have nudged the probability of finding alien civilizations higher.  

Not only that, computing power has caught up, and telescopes are available. SETI researchers have traditionally had to fight for telescope time with astronomers who, frankly, know exactly what they’re looking for. But the Green Bank, Parkes, and Lick Observatories have all suffered funding woes of late, making them more receptive to money from a tech billionaire.

In the half-century since Frank Drake first pointed a radio telescope into space to look for aliens, SETI research has struggled for legitimacy. Scientists have heard nothing but a few bloops, ultimately attributed to things like stray radiation from microwave ovens. 

The search for alien signals is a lot of guesswork, limited by our own technological advancement. As Marcy (who holds the Watson and Marilyn Alberts SETI Chair at Berkeley) points out, we humans wouldn’t have even known to listen for radio signals in the 1890s, and a hundred years before that humans were still communicating with smoke signals. So maybe scientists don’t know what to listen for now.

So what happens if Breakthrough Listen doesn’t find anything?

We’ll roll it over for another 10 years. Why stop? The question is interesting enough to keep going,” said Milner.
