By measuring the rapid orbits of the stars near the center of our galaxy, Dr. Andrea Ghez of UCLA and her colleagues have moved the case for a supermassive black hole at the heart of our Milky Way Galaxy from a possibility to a certainty. She reports on her pioneering observations of stars near our galaxy's center (that orbit the monster black hole) and discusses some of the surprising results this work has led to. The talk was recorded in January 2017; in 2020, Dr. Ghez won the Nobel Prize in physics for this work.

Human-Robotic Exploration from the Moon to Mars 1:12:39

منذ 4 weeks1:12:39

1:12:39

Jan. 29, 2025 Dr. Darlene Lim (NASA Ames Research Center) NASA's Volatiles Investigating Polar Exploration Rover (VIPER) is a planned mission to go to the South Pole of the Moon and get a close-up view of the locations that can sustain water ice – ice that could eventually be harvested to support human exploration on the Moon, on Mars — and beyond. Dr. Lim discusses how, for the first time in NASA’s history, the science team would be fully integrated into the mission operations team and will provide near real-time input on where to explore on the Moon. While the fate of the mission is now in some doubt, Dr. Lim discusses the lessons learned, and the remarkable techniques the team developed to make real-time, almost instant decisions about what the rover does next at each point in its journey. She also tells about how her earlier experience exploring deep lakes on Earth with robotic and crewed vehicles taught her valuable lessons that she could apply to designing lunar exploration protocols.…

منذ 16 weeks1:04:26

1:04:26

Nov. 13, 2024 Dr. Dan Coe (Space Telescope Science Institute) The Webb Telescope was designed to look back in time, to study the first generation of stars, and reveal our cosmic origins. Now in its second year of operation, JWST has already brought us tantalizingly close to our dream of seeing those first stars. Dr. Coe takes us on a tour of some of the latest results from the telescope, and tells us about his and others' observations of the most distant stars and galaxies astronomers have ever seen, providing a view of the universe as it was 13 billion years ago. Dan Coe is an Astronomer at the Space Telescope Science Institute (STScI) and Johns Hopkins University in Baltimore. STScI is home to JWST mission control and science operations, where staff scientists like Dan support other astronomers using Hubble and JWST. Dan has also led the Hubble RELICS and JWST Cosmic Spring science teams in discovering and studying some of the most distant galaxies known in the early universe.…

Profound and Staggering: The Impact on Religion of the Discovery of Life around Other Stars 1:20:58

منذ 21 weeks1:20:58

1:20:58

Recorded Oct. 9, 2024 Astronomers 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.…

The Copernicus Complex: Are We Special in the Cosmos 1:18:53

منذ 28 weeks1:18:53

1:18:53

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…

Black Widow Pulsars: The Vengeful Corpses of Stars 1:01:47

منذ 35 weeks1:01:47

1:01:47

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.…

Europa Clipper: Exploring Jupiter's Ocean World 1:22:35

منذ 41 weeks1:22:35

1:22:35

Presenter is the Project Scientist, Dr. Robert Pappalardo (JPL) May 22, 2024 Jupiter'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.…

The Allure of the Multiverse (with Dr. Paul Halpern) 1:16:29

منذ 46 weeks1:16:29

1:16:29

Apr. 17, 2024 In this talk, physicist and popular author Paul Halpern (St. Joseph's College) examines the history of the concept of a multiverse in science, and discusses the ideas by Einstein and other noted physicists that have led scientist today to take the notion of multiple universes seriously. He also contrasts the scientific view of a multiverse to the picture we get in popular culture (think Marvel movies) and notes how significantly the two differ. Dr. Halpern is the author of a new popular-level book also called "The Allure of the Multiverse" and many other nontechnical science books.…

The Black Hole Wars: My Battle with Stephen Hawking 1:34:51

منذ 47 weeks1:34:51

1:34:51

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 theory for our understanding of reality — a battle that he has described in his well-reviewed book The Black Hole Wars. In this talk Dr. Susskind tells the story of these wars and explains the ideas that underlie the conflict. What's at stake is nothing less than our understanding of space, time, matter and information! Recorded: October 1, 2008 Although this was taped some years ago, this was the most popular talk in the 24-year history of our series. So we wanted to make it available as a podcast, so new audiences could also hear it.…

Black Holes and the Technology to Find Them 1:02:42

منذ 47 weeks1:02:42

1:02:42

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 holes remain unknown, including the true number of black holes in the Galaxy, their masses and sizes, and how the black holes were formed. Dr. Lu discusses how she and other astronomers are using "gravitational lensing" -- something predicted by Einstein’s work -- to open a new window onto black holes, and how the first free-floating black holes are now being discovered. She explains, in everyday language, why astronomers expect that the number of known black holes will increase by a factor of 100 over the next decade.…

Exploring the Gravitational Wave Universe 1:09:36

منذ 1 year1:09:36

1:09:36

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 in space itself, generated by the collision of two black holes. Since then, LIGO and its international partners have measured nearly 100 signals. Dr. Lantz explains what we can learn from these bursts of energy and just how it is possible to measure a wave which stretches our detector 1000 times less than the diameter of a proton. And he discusses what's coming next in our search for these tell-tale ripples in space? Dr. Lantz is the scientific leader for the Advanced LIGO seismic isolation system,…

Water Above, Water Below: The Many Roles of Water in Making Planets Habitable 1:14:58

منذ 1 year1:14:58

1:14:58

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. But it also has many other roles in the evolution of habitable and uninhabitable environments on a planetary scale. In this talk, Dr. Schaefer discusses the ways in which Earth acquired its water, how water modifies the evolution and habitability of the Earth, and how the habitability of rocky planets orbiting other stars may be different. Laura Schaefer is an Assistant Professor of Earth and Planetary Sciences at Stanford University. She is a planetary scientist who focuses on how gases and rocks react with each other to form the atmospheres of rocky planets, both inside and outside the Solar System. The talk was given November 15, 2023.…

The Peril and Profit of Near-Earth Objects 1:10:15

منذ 1 year1:10:15

1:10:15

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 asteroid or comet has markedly diminished in recent decades -- due to diligent astronomical surveys -- but a significant level of danger persists. At the same time, remarkable strides have been made in advancing technologies that pave the way for a new vision of space exploration – one that involves missions and outposts within the inner solar system fueled by resources extracted from near-Earth asteroids. These objects contain exploitable extraterrestrial resources delivered free to the inner solar system, and they have been naturally preprocessed into objects the ideal size for industrial operations. Robert Jedicke obtained his Ph.D. in experimental particle physics from the University of Toronto and held post-doctoral positions at the Fermi National Accelerator Laboratory and at the University of Arizona’s Lunar & Planetary Laboratory. At the University of Hawai`i’s Institute for Astronomy for the last 20 years, he managed the development of the Moving Object Processing System for the Pan-STARRS telescope on Maui.…

SPECIAL: An Interview with Frank Drake: The Founder of SETI Science (conducted by Andrew Fraknoi) 44:02

منذ 2 years44:02

44:02

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 SETI Institute sponsored a three-day public event called SETICon. One highlight of the program was an interview with Drake (who served as the founding President of the Institute board. ) It was conducted by SETI Institute board member and veteran astronomy educator Andrew Fraknoi. The discussion ranged widely over Dr. Drake's career and current thinking. It included reminiscences of Project OZMA, that first experiment searching for signals from civilizations among the stars, and his current view of the Drake Equation. He also reflects on a number of modern developments, including the discovery of numerous planets orbiting other stars and new ways of searching for extra-terrestrial civilizations. During the Summer, when the Silicon Valley Astronomy Lectures take a vacation, we thought you might enjoy this special podcast for its historical value, now that Frank Drake has passed away.…

An Eclipse Double-Header: Two North American Eclipses of the Sun in 2023 & 2024 (with Andrew Fraknoi) 1:02:49

منذ 2 years1:02:49

1:02:49

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 eclipses are unique), the circumstances of each coming eclipse and where each will be visible, plus how to view eclipses safely. He shows maps of the eclipse paths and provides URLs to where you can get free information materials to help you enjoy eclipses without hurting your eyes, wherever you are.
