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.)

The Black Hole Wars: My Battle with Stephen Hawking

Apr 15 2024 94 mins  
With Dr. Leonard Susskind (Stanford University)Black holes, the collapsed remnants of the largest stars, provide a remarkable laboratory where the frontier concepts of our understanding of nature are tested at their extreme limits. For more than two decades, Professor Susskind and a Dutch colleague had a running battle with Stephen Hawking about the implications of black hole theor

Black Holes and the Technology to Find Them

Apr 10 2024 62 mins  
A Non-technical Talk by Dr. Jessica Lu (University of California, Berkeley) on March 13, 2024The 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 holes remain unknown, including the true number of black holes in th

Exploring the Gravitational Wave Universe

Feb 20 2024 69 mins  
Speaker: Dr. Brian Lantz (Stanford University)Feb. 7, 2024Measuring 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 in space itself, generated by the collision of two black holes. Si

Water Above, Water Below: The Many Roles of Water in Making Planets Habitable

Dec 04 2023 74 mins  
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 touches. Water is crucial to life, both as a habitat and as a solvent.

The Peril and Profit of Near-Earth Objects

Oct 29 2023 70 mins  
A Talk by Dr. Robert Jedicke (U of Hawaii)Oct. 11, 2023Near-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 asteroid or comet has markedly diminished in recent decades -- due to

SPECIAL: An Interview with Frank Drake (conducted by Andrew Fraknoi)

Jul 17 2023 44 mins  
June 2012Frank 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 SETI Institute sponsored a three-day public event called S

Ashes to Ashes, Earth to Earth, Dust to Dust: The Birth and Death of Worlds

Jul 13 2023 65 mins  
with Dr. Eugene Chiang (University of California, Berkeley)June 21, 2023We 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 story combines the latest observations from a wide range of telesco

An Eclipse Double-Header: Two North American Eclipses of the Sun in 2023 & 2024 (with Andrew Fraknoi)

May 17 2023 62 mins  
North America will be treated to two eclipses of the Sun in the 2023-24 school year: an annular eclipse on Oct. 14, 2023 and a total eclipse on Apr. 8, 2024. Some 500 million people will be in a position to see at least a partial eclipse on each date. Astronomer Andrew Fraknoi (Fromm Institute, University of San Francisco) discusses the cause of eclipses (and why Earth's eclip

The First Results from the James Webb Space Telescope (with Dr. Alex Filippenko)

Mar 12 2023 89 mins  
Dr. Alex Filippenko (University of California, Berkeley)Mar. 8, 2023We have a new supersensitive eye in the cosmic sky. Parked nearly one million miles from Earth, the James Webb Space Telescope (JWST) is 100 times more sensitive than the Hubble Space Telescope. JWST observes at the red to the mid-infrared parts of the spectrum, offering new insights into a vast array of objects an

Our Boldest Effort to Answer our Oldest Question: Breakthrough-Listen Search for Intelligent Life

Feb 19 2023 85 mins  
For centuries, humans have gazed at the night sky and wondered if any intelligent life forms like us might be out there. In 2015, the Breakthrough Foundation gave a $100 million grant to the University of California at Berkeley to undertake the most comprehensive search for signals from an extra-terrestrial civilization. Dr. Steve Croft, of the University of California, Berkeley, S
