    Heino Falcke and Jörg Römer, "Light in the Darkness: Black Holes, the Universe, and Us" (HarperCollins, 2021)
    Jan 9 2026
    An astrophysicist chronicles his quest to photograph a black hole and reflects on its spiritual ramifications in this international-bestselling memoir. On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference—a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke's goal in making a black hole "visible" for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.Light in the Darkness takes us on Falcke's extraordinary journey to the darkest corners of the universe. From the first humans looking up at the night sky to modern astrophysics, from the study of black holes to the still-unsolved mysteries of the universe, Falcke asks, in even the greatest triumphs of science, is there room for doubts, faith, and a God? A plea for curiosity and humility, Light in the Darkness sees one of the great minds shaping the world today as he ponders the big, pressing questions that present themselves when we look up at the stars.

    Jeremy Bernstein 11–2007
    Dec 10 2025
    In this episode from the Institute’s vault, we revisit an October 2007 presentation by theoretical physicist and Institute Fellow Jeremy Bernstein on J. Robert Oppenheimer, the atomic bomb, and the nuclear arms race that followed. As a physicist, Bernstein made contributions to elementary particle physics and cosmology, working at the Institute for Advanced Study in Princeton, New York University, and Stevens Institute of Technology, where he became Professor Emeritus in 1967. He held visiting positions at CERN, Oxford, and the École Polytechnique, among others, and was the last surviving senior member of Project Orion, which studied the potential of nuclear pulse propulsion for space travel. Bernstein was a staff writer for The New Yorker for over three decades. He wrote regularly for The New York Review of Books, The Atlantic Monthly, and Scientific American, and authored over two dozen books, including Oppenheimer: Portrait of an Enigma (2004). He passed away on April 20th, 2025 at the age of 95. Here he is in 2007, discussing the topics on which he made a great contribution and helped illuminate. Learn more about your ad choices.

  • Jon Willis, "The Pale Blue Data Point: An Earth-Based Perspective on the Search for Alien Life" (U Chicago Press, 2025)

    Jon Willis, "The Pale Blue Data Point: An Earth-Based Perspective on the Search for Alien Life" (U Chicago Press, 2025)
    Dec 3 2025
    A thrilling tour of Earth that shows the search for extraterrestrial life starts in our own backyard.Is there life off Earth? Bound by the limitations of spaceflight, a growing number of astrobiologists investigate the question by studying life on our planet. Astronomer and author Jon Willis shows us how it’s done, allowing readers to envision extraterrestrial landscapes by exploring their closest Earth analogs in The Pale Blue Data Point: An Earth-Based Perspective on the Search for Alien Life (U Chicago Press, 2025). With Willis, we dive into the Pacific Ocean from the submersible-equipped E/V Nautilus to ponder the uncharted seas of Saturn’s and Jupiter’s moons; search the Australian desert for some of Earth’s oldest fossils and consider the prospects for a Martian fossil hunt; visit mountaintop observatories in Chile to search for the telltale twinkle of extrasolar planets; and eavesdrop on dolphins in the Bahamas to imagine alien minds.With investigations ranging from meteorite hunting to exoplanet detection, Willis conjures up alien worlds and unthought-of biological possibilities, speculating what life might look like on other planets by extrapolating from what we can see on Earth, our single “pale blue dot”—as Carl Sagan famously called it—or, in Willis’s reframing, scientists’ “pale blue data point.” Learn more about your ad choices.

    Andrew H. Jaffe, "The Random Universe: How Models and Probability Help Us Make Sense of the Cosmos" (Yale UP, 2025)
    Nov 25 2025
    An award-winning astrophysicist looks at how the understanding of uncertainty and randomness has led to breakthroughs in our knowledge of the cosmos All of us understand the world around us by constructing models, comparing them to observations, and drawing conclusions. Scientists create, test, and replace these models by applying the twinned concepts of probability and randomness. Exploring how this process has refined our knowledge of quantum mechanics and the birth of the universe, In The Random Universe: How Models and Probability Help Us Make Sense of the Cosmos (Yale UP, 2025) Andrew H. Jaffe offers a unique synthesis of the philosophy of epistemology, the mathematics of probability, and the science of cosmology. As Jaffe puts Enlightenment thinkers like David Hume in conversation with contemporary philosophers such as Karl Popper and Imre Lakatos and engages with scientists ranging from Isaac Newton and Galileo to Albert Einstein and Arthur Eddington, he uses Thomas Bayes's seminal studies of statistics and probability to make sense of conflicting currents of thought. This is a deep look into how we have learned to account for uncertainty in our search for knowledge--and a reminder that science is not about facts and data as such but about creating models that correctly account for those facts and data.

    Craig Hogan, "The Unlikely Primeval Sky" (American Scientist, November-December)
    Nov 13 2025
    Of all the patterns that could possibly be preserved in the post–Big Bang radiation, the one we see is surprisingly smooth on large angular scales. Sitting by a campfire on a dark night, looking up at the Milky Way, a curious child asks, “What does the sky tell us? Where does it all come from? Does space go on forever?” A caring adult might share a little awe and humility about humanity’s place in the grand scheme or perhaps relate a traditional creation story. A scientist like me, who came of age soon after the discovery that the sky is not actually dark but awash in primeval radiation, might instead relate the still-unfinished scientific story of the boundaries and origins of time and space. That tale is displayed in nature’s own record of the structure of the early universe, a mosaic of temperature and density fluctuations preserved in the primordial light that astronomers call the cosmic microwave background (CMB).

  • Facing Infinity: Black Holes and Our Place on Earth

    Facing Infinity: Black Holes and Our Place on Earth
    Nov 13 2025
    Humanity’s relationship with black holes began in 1783 in a small English village, when clergyman John Michell posed a startling question: What if there are objects in space that are so large and heavy that not even light can escape them? Almost 250 years later, in April 2019, scientists presented the first picture of a black hole. Profoundly inspired by that image, physicist Jonas Enander has traveled the world to investigate how our understanding of these elusive celestial objects has evolved since the days of Michell. With the particular goal of discovering our human connection to black holes, Enander visits telescopes and observatories, delves deeply into archives, and interviews over 20 world-leading experts, including several Nobel laureates. In Facing Infinity: Black Holes and Our Place on Earth (The Experiment, 2025), Dr. Enander takes us on a spellbinding journey into the universe’s greatest mystery, deciphers the most mind-bending science, and answers questions surrounding how black holes work, where they come from, and what role they play in the universe. Along the way, he discovers how our desire to understand black holes inadvertently paved the way for the invention of Wi-Fi and the calibration of our global navigation satellites, how astronomical discovery became entangled with colonial conflicts, and how our looking outward gave us critical evidence of the impact of climate change. Facing Infinity helps us appreciate and understand as never before these mysterious celestial objects and our surprising connections to them. Our guest is: Dr. Jonas Enander, who is a science communicator with a background in cosmology and astrophysics. His previous research focused on dark matter and Einstein’s theory of general relativity. He has worked as a physics teacher at the KTH Royal Institute of Technology in Stockholm, and participated in the construction of the IceCube Neutrino Observatory at the South Pole. He hosts the podcasts Spacetime Fika and Rumtiden. Our host is: Dr. Christina Gessler, who is a freelance editor. She is the producer of the Academic Life podcast, and writes the show’s newsletter at ChristinaGessler.Substack.Com.

    What is space? What is time? Where did the universe come from? The answers to mankind's most enduring questions may lie in science's greatest enigma: black holes.A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. This can occur when a star approaches the end of its life. Unable to generate enough heat to maintain its outer layers, it shrinks catastrophically down to an infinitely dense point.When this phenomenon was first proposed in 1916, it defied scientific understanding so much that Albert Einstein dismissed it as too ridiculous to be true. But scientists have since proven otherwise. In 1971, Paul Murdin and Louise Webster discovered the first black hole: Cygnus X-1. Later, in the 1990s, astronomers using NASA's Hubble Space Telescope found that not only do black holes exist, supermassive black holes lie at the heart of almost every galaxy, including our own. It would take another three decades to confirm this phenomenon. On 10 April 2019, a team of astronomers made history by producing the first image of a black hole.A Crack in Everything: How Black Holes Came in from the Cold and Took Cosmic Centre Stage (Apollo, 2025)is the story of how black holes came in from the cold and took cosmic centre stage. As a journalist, Marcus Chown interviews many of the scientists who made the key discoveries, and, as a former physicist, he translates the most esoteric of science into everyday language. The result is a uniquely engaging page-turner that tells one of the great untold stories in modern science. Learn more about your ad choices. Visit megaphone.fm/adchoices
