Silicon Valley Astronomy Lectures

Recorded Oct. 9, 2024Astronomers have now discovered thousands of planets in orbit around other stars. Dr. Weintraub discusses those discoveries, and predicts the progress astronomers are likely to make in their more detailed studies of these planets over the next fifty years. Then he considers the consequences of those potential discoveries for Roman Catholicism, Mainline Protestantism, Christian Creationism, Seventh Day Adventism, Judaism, Islam, and Hinduism -- for all of which the discovery of a planet with life on it may be profound. These thoughts are based on the writings of key religious leaders on this topic -- in the past and in our times.Dr. David A. Weintraub is Professor of Astronomy Emeritus at Vanderbilt University where he founded and directed the Communication of Science and Technology program, and conducted research on the formation of stars and planets. His most recent book is The Sky is for Everyone: Women Astronomers in Their Own Words (2022; with Virginia Trimble). Previous books include Religions and Extraterrestrial Life: How Will We Deal With It? (2014), Life on Mars: What to Know Before We Go (2018), How Old is the Universe? (2010), and Is Pluto a Planet? (2006). He also created the Who Me? series of inspirational scientific autobiographies for fifth-grade level readers (from World Scientific Publishing), which helps young people see themselves as scientists.

With Prof. Caleb Scharf (Columbia University)Is humanity on Earth special or unexceptional?  Extraordinary discoveries in astronomy and biology have revealed a universe filled with endlessly diverse planetary systems, and a picture of life as a phenomenon intimately linked with the most fundamental aspects of physics. But just where these discoveries will lead us is not yet clear.  We may need to find a way to see past the mediocre status that Copernicus assigned to us 500 years ago.  Dr. Scharf helps us to come to grips with the implications of some of the latest scientific research, from the microscopic to the cosmic.Caleb Scharf is Director of Astrobiology at Columbia University in New York and is considered one of the leading scholars at the interface of astronomy and biology.  He is the author of the popular book Gravity’s Engines, which was the basis of the BBC/Science Channel documentary, Swallowed by a Black Hole.  His textbook, Extrasolar Planets and Astrobiology won the 2011 Chambliss Prize.   His book, The Copernicus Complex, was published by Scientific American/Farrar, Straus and Giroux; Recorded October 2014

With Dr. Roger Romani (Stanford University):NASA's Fermi Gamma-ray Space Telescope has revealed a violent high-energy universe full of stellar explosions, black hole jets, and pulsing stars.  These cosmic objects are often faint when observed with visible light, but glow bright with gamma rays.   Dr. Romani describes the quest to discover the true nature of the most puzzling of these gamma-ray sources.  Several turn out to be a kind of bizarre star corpse called a 'black widow' pulsar -- where a dead star has a companion that it is slowly destroying.This is a talk from 2014, but it is still relevant today.

Presenter is the Project Scientist, Dr. Robert Pappalardo (JPL)May 22, 2024Jupiter's moon Europa may be a habitable world, containing the “ingredients” necessary for life within its ocean. Data from NASA’s earlier Galileo mission suggest that a global, salty ocean exists beneath the icy surface. Tides have broken that floating ice shell to create impressive ridges, bands, and chaotic terrains. The Europa Clipper mission will explore Europa with a suite of instruments, through multiple close flybys from Jupiter orbit, examining the moon’s ice shell, ocean, and geology.  And it will search for current activity –including plumes that emerge from surface cracks. Dr. Pappalardo, the mission's Project Scientist, summarizes our understanding of Europa and the and status and promise of the Europa Clipper.
