Dr. Jill Tarter, Astronomer and Director of the Center for SETI Research at the SETI Institute in Mountain View, California explains the technology and significance of NASA's Kepler, which detects when stars "blink" or a planet passes in front of it, and her role in SETI, the Search for Extraterrestrial Intelligence. With the use of Kepler, Tarter tells us that there are probably about 50 billion planets in the Milky Way galaxy, of which 500 million are potentially habitable. So, she asks, are we alone? Tarter explains her research with SETI involving new ways to search for biosignatures around these planets that indicate extraterrestrial life.
The SETI Institute's Jill Tarter makes her TED Prize wish: to accelerate our search for cosmic company. Using a growing array of radio telescopes, she and her team listen for patterns that may be a sign of intelligence elsewhere in the universe.

Is anyone out there? For over 40 years scientists have been searching for extraterrestrial intelligence, but they've found nothing. Now the new Allen Telescope Array, a string of 350 radio telescopes, is being built 300 miles north of San Francisco and is breathing new life into the search. Find out why SETI scientists now say we might be hearing from ET sooner than you think.
