Dr. Jill Tarter of the SETI Institute is the leader of the main project looking for radio signals from alien civilizations (she was also the model for the character Jodie Foster played in the movie "Contact.") She updates us on the latest tools and plans in this quest, as digital technologies make possible huge improvements in our search systems. The Allen Telescope Array, being constructed in Northern California, will be the most powerful tool for finding SETI signals ever built. It is an innovative radio telescope assembled from a large number of small dishes, using consumer off-the-shelf technologies whenever possible to minimize costs. In the next decade, this new instrument will enable exploration that is 1000 to 10,000 times more sensitive than in the previous decades. This may just be enough! Recorded April 23, 2008.
