Kilonova Metals; Cat Ecology – Apr 29
Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley astrophysicist Daniel Brethauer on Astronomically Rocking Out to Heavy Metals — The gold in jewelry, the uranium in a nuclear power plant, the caesium in atomic clocks: what do these all have in common? It turns out they were likely forged in the fires of a cosmic explosion known as a kilonova. These extremely energetic events reveal the origins of the periodic table’s heaviest elements.
• UC Berkeley ecologist Tyus Williams on Unraveling the Ecology of Domestic Cats — What if one of our greatest companions is potentially one of our greatest threats? When free to roam, domestic cats can severely disrupt wildlife communities. However, understanding cats’ behavior and how they’re influenced by their surroundings can allow us to develop better conservation strategies.

Eye Movements; Tiny Galaxies – Apr 15
Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley neuroscientist Stephanie Reeves on The Horizontal Saccade Bias — Humans make eye movements to explore the visual environment. One type of involuntary eye movement, termed a saccade, occurs 2-3 times per second and is one of the fastest movements that the human body can make. New research challenges previous assumptions about how and why saccades arise.
• Stanford astrophysicist Viraj Manwadkar on Tiny Galaxies and Big Cosmic Mysteries — The very smallest galaxies shed light on fundamental questions in physics and astronomy: They play an intriguing role in the formation of cosmic ecosystems, and they even inform our attempt to understand dark matter, the utterly mysterious stuff that constitutes 80% of the material universe.

Black Holes; Kelp Forests – Feb 24
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley astrophysicist Natasha Abrams on Black Holes: Discovering the Invisible — Black holes are among the most extreme objects in the universe. They push the boundaries of our knowledge, holding many unsolved mysteries. This talk will explore black holes from “small” to enormous, including how to detect these invisible marvels. In the process, we will probe the very frontiers of astrophysics.
• Stanford marine biologist Will Johnson on The Structure of Kelp Forests — Kelp forests constitute one of the most diverse ecosystems on Earth, and they’re hidden right beneath the waves of our coastline. To research how these ecosystems function, we need to study what lives there. Come learn how scientific diving and modern genetics are helping us unravel the complex structure of kelp forests.

Scavengers+DarkMatter+Biomolecules – Jul 16
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these three Science Envoys will answer questions with insight and enthusiasm:
• Stanford ecologist Chinmay Sonawane on How Scavenging Animals Protect Human Health — Wildlife is rapidly disappearing globally. But why should we care? The loss of scavengers (consumers of already-dead animals) provides an intriguing example of how biodiversity loss has had, and will continue to have, profound consequences for human health.
• UC Berkeley physicist Bethany Suter on Direct Detection of Dark Matter — Ubiquitous, yet deeply mysterious, dark matter constitutes 85%(!) of the material universe. What do we know — and not know — of elusive dark matter particles? Novel laboratory materials may allow us to detect dark matter directly, shining light into the pervasive cosmic shadows.
• Stanford biophysicist Sean Waterton on Making Biomolecules from Electricity — Solar panels produce ever-more clean electricity. At the same time, human activity produces copious amounts of CO2. Modern research in synthetic biology allows us to use electricty and CO2 to create valuable molecules like fats and proteins — and, hopefully, more specialized molecules like medications.

Fast & Faraway – Nov 28
In astronomy, the redder a galaxy appears, the faster it is fleeing, and the older a tale its light can tell. Such “redshifts” in the spectra of galaxies (symbolized with the letter “z”) allow compelling cosmic insights. The recently-launched James Webb Space Telescope (JWST) has allowed astronomers to study the properties of high-z galaxies in existence only 250 million years after the Big Bang, when the universe was only 2% of its current age! How are these objects detected in such very “deep” space, and what are the early science results from this JWST research?
Our speaker is Dr. Thomas Targett, Associate Professor of Physics & Astronomy at the Sonoma campus of California State University. Dr. Targett’s Wonderfest history includes an eye-opening talk entitled Popular Myths of Astronomy, presented as part of the Mt. Tam Astronomy Program.

Search for ET – Oct 15
Humans have sought “signs from above” for millennia. The scientific search for extraterrestrial intelligence (SETI) began circa 1960, and, today, grows ever deeper and more technologically diverse. The scope of modern research is breathtaking. Methods include targeted searches for electromagnetic (EM) signals near known Earth-like exoplanets, continuous EM scans over the entire sky (e.g., PANOSETI at the Bay Area’s Lick Observatory, pictured), the hunt for exotic forms of communication, and the careful search for ET artifacts on/near Earth.
Our speaker, Dan Werthimer, is Chief Scientist at the Berkeley SETI Research Center. He is also co-founder of SETI@Home, and principal investigator of CASPER, the Center for Astronomy Signal Processing and Electronics Research. Since 1979, Dan has helped to design and build numerous sensitive tools for the detection of ET. In 2019, Dan earned Wonderfest’s Carl Sagan Prize for Science Popularization. And, in 2021, he received the prestigious Frank Drake Award of the SETI Institute.

Extraterrestrial Life – Sep 5
An August-24th New York Times article about audacious astronomer Avi Loeb concludes with this: “Now, that being said, if [Dr. Loeb] finds something, it’s life-changing … It will change everything.” What was “being said” referred to professional academic complaints about Dr. Loeb’s alleged “transgressions against scientific norms and protocols.” However, no one disputes the excitement of Prof. Loeb’s investigations. Wonderfest joins the Commonwealth Club to present controversial Harvard astronomer Avi Loeb in conversation about ideas in his latest book, Interstellar: The Search for Extraterrestrial Life and Our Future in the Stars. That conversation will explore some vital — if highly speculative — long-term questions: How do we prepare for first contact with ET? And how can our species itself become interstellar?
Dr. Avi Loeb is Professor of Science and former chair of the Astronomy Department at Harvard University. During this online event, he will be in conversation with the Commonwealth Club’s George Hammond.

Astronomy for Earth – June 20
The past few decades of astronomical discovery have been breathtaking: thirty years of awe-inspiring images from two Space Telescopes (Hubble & Webb), thousands of planets found circling nearby stars, mind-bending and spacetime-bending gravity waves and, quite recently, a stunning image of the black hole at the center of the Milky Way. What is the value of all of these discoveries? Can learning about our place in the Universe inspire us, as Carl Sagan put it, to preserve and cherish the Pale Blue Dot?
Our speaker, Dr. Adrienne Cool, is Professor of Physics & Astronomy at San Francisco State University. She is also co-founder of Astronomers for Planet Earth, an international organization working to address climate change from a cosmic perspective.

Biodiversity; Cosmic Maps – Mar 27
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• Stanford paleobiologist Dr. Maria Viteri on Exhuming the Dead to Save the Living — Earth is experiencing a crisis in biodiversity. Surprisingly, the fossil record offers key insights for understanding this crisis, and one scientist’s lifelong fascination with dinosaurs — leading to a career in conservation biology — is helping to combat the biodiversity challenge of the present … and of the future.
• UC Berkeley astrophysicist Tyler Cox on Creating the Largest-Ever Maps of the Universe — New datasets from the James Webb Space Telescope have begun to reveal some of the oldest known galaxies in the universe. But what lies beyond these extremely remote objects, and what more can we learn by going deeper? Next-generation experiments are working to map the most distant regions of the universe to help explain the origins of the first galaxies.

• UC Berkeley arachnologist Trinity Walls on Creepy or Captivating: A Spider Scientist’s Perspective — How have recent discoveries about spiders changed beliefs that have been passed down for generations? Can we see that the study of spiders is beneficial to society? One person’s life-long journey — from curious child to rigorous researcher — reveals spider science to be an avenue of creative self-expression that offers rich insights into nature.
• Stanford physicist Jyotirmai “Joe” Singh on Exploring the Dark Side of the Universe — Deeply mysterious dark matter constitutes a staggering 85% of the material universe. What is the evidence for dark matter’s ubiquitous existence, yet why has it been so difficult to detect in the laboratory? Cutting-edge theories and experiments within modern physics do give us hope that we can understand dark matter, unlocking key mysteries of the cosmos.

Plant Immunity; Exoplanets – Mar 30
Wonderfest Science Envoys are early-career researchers with special communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley plant biologist Chandler Sutherland on It’s Not Easy Staying Green: Understanding Plant Immune Systems — Every day, plants resist an onslaught of viruses, bacteria, fungi, and herbivores. However, plants can’t make antibodies or move immune cells around with a circulatory system, as we can. Understanding plant immune systems teaches us about how human immunity evolved, and is helping us learn how to protect our agricultural crops against disease.
• Stanford astrophysicist Alex Madurowicz on Imaging Extrasolar Planets — Technical advancements in the next decade will enable telescopic observation of smaller and fainter worlds that orbit other stars, including Earth-like planets. Going further, bold concepts for the next century completely reimagine the concept of a telescope — allowing resolution of details like continents, forests, and even extraterrestrial cities.

How the First Things in the Universe Came About and How They Ended Up Within Us, Oct 5
Join us for a fascinating journey through the early universe using the latest computer animations of early star formation, supernova explosions, and the build-up of the first galaxies. Dr. Abel’s work has shown that the first luminous objects in the universe were very massive stars shining one million times as brightly as our Sun. They died quickly and seeded the cosmos with the chemical elements necessary for life. One star at a time, galaxies started to assemble just one hundred million years after the Big Bang, and they are still growing now. Computer simulations of these events use the physics of dark matter, of ordinary atoms & molecules, and of expanding space to deliver remarkable insights into the early history of the cosmos.

The Milky Way as a Dark Matter Laboratory
![]() |
Co-Sponsored with the Mt. Tam Astronomy Program8:30 PM, Saturday, June 23Mountain Theater, MarinMichael Kuhlen, Postdoctoral Fellow at the Theoretical Astrophysics Center, UC BerkeleyMore than 80% of the material universe consists of stuff we don’t understand. This “dark matter” gravitates, but it does very little else; in particular, it doesn’t emit, reflect, or even absorb light. Over the next decade, a combination of astronomical observations and particle physics experiments hold great promise to finally shed light on the nature of dark matter. This lecture will be followed by a guided tour of the night sky provided by Paul Salazar, the Urban Astronomer. Then, true space cadets are invited to walk to the nearby Rock Spring parking lot to peer through telescopes of the San Francisco Amateur Astronomers. |
