Russian Millionaire Looking for Aliens

Wondering if we are alone in the universe has engaged minds through the ages. Add to the list Russian billionaire Yuri Milner, who announced on Monday that he plans to spend $100 million to explore the idea.
Using some of the world's largest radio telescopes, a team of scientists handpicked by Milner will oversee an initiative he calls Breakthrough Listen, a 10-year search for radio signals that could indicate the existence of intelligent life elsewhere in the universe, according to Reuters.
"It's the most interesting technological question of our day," Milner said in an interview, noting that he became fascinated by the notion of extraterrestrial life after reading astrophysicist Carl Sagan's "Intelligent Life in the Universe" as a 10-year-old in Moscow.
His funds to bankroll the project came from savvy early investments in startups such as Facebook Inc. Milner's motivation is his belief that other civilizations could teach us how to handle challenges such as allocating natural resources.
"If we're alone, we need to cherish what we have," he said. "The message is the universe has no backup."
Scientists said the project dwarfs anything else in the field, known as the Search for Extraterrestrial Intelligence. Globally, less than $2 million annually are spent on SETI, said Dan Werthimer, an adviser to Milner's project and the astrophysicist who directs the SETI@home project affiliated with the University of California in Berkeley.
Today, due to technology improvements, including in computing power and telescope sensitivity, $100 million will go much farther than in the early 1990s, the last time SETI had significant funding, scientists said.
The advances allow scientists to monitor several billion radio frequencies at a time, instead of several million, and to search 10 times more sky than in the early 1990s.
But any signals the scientists detect will likely have been created years ago, perhaps even centuries or millennia earlier. Radio signals take four years simply to travel between Earth and the nearest star outside our solar system. In 10 years, with his $100 million, Milner figures scientists can listen for radio transmissions in the Milky Way galaxy, plus the 100 nearest galaxies.
One of the biggest costs lays in booking time at radio telescopes, including at Australia's Parkes Observatory in New South Wales and the Radio Astronomy Observatory in Green Bank, West Virginia.  Milner plans to book about two months a year at each site, a boon to scientists who normally might get two days a year on the telescopes. The team, led by scientists such as Peter Worden, who until earlier this year directed the NASA Ames Research Center, will organize the radio signals they find, make the data public and examine the data for patterns.
