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 Non-technical Talk by Dr. Jessica Lu (University of California, Berkeley) on March 13, 2024 The population of black holes, objects left over from dead stars, is almost entirely unexplored. Only about two dozen black holes are confidently known in our Galaxy. As a result, some of the most basic properties of black ho
Speaker: Dr. Brian Lantz (Stanford University) Feb. 7, 2024 Measuring gravitational waves is a revolutionary new way to do astronomy. They were predicted by Einstein, but it was not until 2015, that LIGO (the Laser Interferometer Gravitational-wave Observatory) first detected one of these waves. They were tiny ripples
Dr. Laura Schaefer (Stanford University): Water is everywhere. Its atoms, hydrogen and oxygen, are the first and fifth most abundant elements in the universe. Water is found in abundance in many environments; it finds its way into planets of all shapes and sizes, where it modifies the properties of everything it touche
A Talk by Dr. Robert Jedicke (U of Hawaii) Oct. 11, 2023 Near-Earth objects present both an existential threat to human civilization and an extraordinary opportunity to help our exploration and expansion across the solar system. Dr. Jedicke explains that the risk of a sudden, civilization-altering collision with an ast
June 2012 Frank Drake (1930-2022) was known as the "father of SETI science" -- he was the scientist who conducted the first radio survey for signals from extraterrestrial civilizations, and came up with the formula for estimating the likelihood of such civilizations, now called the Drake Equation. In June 2012, the SE
with Dr. Eugene Chiang (University of California, Berkeley) June 21, 2023 We now know that our solar system is but one of countless others. Where did all these planets come from? What are their fates, and ours? Dr. Chiang describes the life cycle of planets, how they are born and die, and how they are born again. The s
