Silicon Valley Astronomy LecturesAuthor: Silicon Valley Astronomy Lectures
Listen to exciting, non-technical talks on some of the most interesting developments in astronomy and space science. Founded in 1999, the Silicon Valley Astronomy Lectures are presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers include a wide range of noted scientists, explaining astronomical developments in everyday language. The series is organized and moderated by Foothill's astronomy instructor emeritus Andrew Fraknoi and jointly sponsored by the Foothill College Physical Science, Math, and Engineering Division, the SETI Institute, the Astronomical Society of the Pacific, and the University of California Observatories (including the Lick Observatory.)

A nontechnical talk by Dr. Bruce Macintosh (University of California Observatories)Mar. 11, 2026In the past three decades, more than 6000 planets have been discovered orbiting other stars. Advances in technology have allowed a handful of giant planets around other stars to be imaged directly. Dr. Macintosh tells us about the first-ever images of other solar systems — and the technology that has allowed us to discover them, such as the Gemini Planet Imager — as well as the future planet-hunting space telescopes. The ultimate goal is detection of a second ‘pale blue dot’ — an Earth twin where we could even see the biosignatures of extrasolar life. (He also talks a bit about the wind damage to the Lick Observatory and what is being done to repair the historic dome.)Bruce Macintosh is the Director of the University of California Observatories in California and Hawaii. He co-led the team that imaged the first extrasolar planets, and was the Principal Investigator of the Gemini Planet Imager, an advanced planet-finder for the Gemini South telescope.
