How did we go from knowing a handful of planets in our own solar system to confirming thousands of worlds around other stars?

This episode traces the story of exoplanets, from ancient “wanderers” in the night sky to the modern methods astronomers use to detect worlds we usually can’t see directly. We talk Galileo, Jupiter’s moons, hot Jupiters, pulsar planets, lava worlds, water worlds, rogue planets, Planet 9, and why the universe keeps handing us planets we never expected.

This episode starts with the story behind the science: how a football injury, a lost sense of identity, and a Cosmos documentary helped send me toward astronomy and exoplanet research.

From there, we get into what my dissertation was actually about: atmospheric mass loss for close-in exoplanets. That means planets getting blasted by radiation from their stars, losing gas over time, and sometimes leaving behind clues we can detect from Earth. We talk Mars, Venus, hot Jupiters, helium escape, WASP-69b, the radius gap, young planets, and why understanding atmospheres matters for the search for life.

What would alien astronomers see if they pointed an impossible telescope at Earth from millions of light-years away?

This episode uses that thought experiment to explain light travel time, relativity, time dilation, the Andromeda paradox, and the strange idea that there may be no single universal “now.” We also get into the block universe, why GPS depends on relativity, and what all of this might mean for how we think about the future.

This is the first installment in the astrobiology series, adapted from the astrobiology course Dr. Dakotah Tyler taught at university. Expect to learn what astrobiology actually means, why sci-fi aliens are usually too human, why UFO claims require careful assumptions, and why defining life is harder than it sounds. We cover viruses, dormant microbes, ideas as information systems, chemical possibility, life as a physical process, habitability, synthetic life and biosignatures. As always, lead with curiosity.

June Sass is a public health scientist and microbiologist with a master’s from Johns Hopkins in molecular microbiology and immunology. Her work connects fungal biology, public health, pathogens, therapeutics, astromycology, and the microbiome. She also runs Summercraft Kombucha, where she develops mushroom kombucha and wellness drinks.

Expect to learn why fungi and bacteria are not just harmful pathogens, but also essential parts of our health, our ecosystems, and the story of life on Earth. We talk about how microbes compete, cooperate, adapt, survive extreme environments, and sometimes behave in ways that start to feel strangely intelligent.

The conversation also covers kombucha, symbiosis, NASA clean rooms, fungi in space, extremophiles, panspermia, the origin of life, alien biology, the deep ocean, antibiotics, antifungals, microbial defense systems, and the weird power of tiny life.

Qasim Rashid is a human rights and civil rights attorney, author, advocate, and the founder of Let’s Address This. His work focuses on justice, democracy, human rights, and public discourse, but this conversation turned into a wide-ranging exploration of science, society, faith, sci-fi, and the future.

Expect to learn how an astrophysicist and a human rights attorney ended up talking about alien life, Project Hail Mary, relativity, intelligent whales, faith, the Quran and astronomy, black holes, dark matter, dark energy, space law, human rights in future space colonies, and why curiosity matters in an age of anti-intellectualism.

We also talk about The Expanse, Interstellar, Contact, The Last Question, The Space Traders, whether intelligent life might exist in our galaxy, and one biology fact about mitochondria that still blows my mind.

Dr. Natasha Latouf is an astrobiologist, NASA Fellow, and PhD physicist studying how we could detect Earth-like life on nearby Earth-like planets.

Expect to learn what astrobiology actually is, how scientists search for biosignatures, why oxygen is both useful and dangerous, why UFOs and UAPs probably are not aliens, and what future telescopes may be able to detect in the atmospheres of small rocky planets.

We also talk about Dr. Latouf’s BARBIE code, K2-18b, extremophiles, Mars, Venus, viruses, whether life may be almost impossible to fully kill, and whether we might confirm alien life in our lifetime.

This is Part 2 of the Dr. StarKid astrobiology series.

Before we can talk seriously about life beyond Earth, we have to understand how humans figured out Earth was not the center of everything. This episode walks through the ideas, assumptions, observations, and arguments that moved us from ancient skywatching to modern astrophysics.

Expect to learn about ancient debates over infinite worlds, human pattern recognition, the night sky as an early scientific tool, planets as “wanderers,” retrograde motion, epicycles, Copernicus, Kepler, Newton, Galileo, and Einstein’s update to gravity.

We also get into Tycho Brahe’s brass nose and drunk moose, Kepler’s laws of planetary motion, why orbits work, and why this history matters for astrobiology.

This version has the corrected audio

Tony Baker is a comedian, actor, creator, and lifelong astronomy fan who came into this conversation ready with the National Geographic space book that first got him hooked as a kid.

Expect to learn how Tony thinks about space, comedy, God, science, acting, stand-up, observation, crows, astrology, astronomy, alien life, and the absurd luck of existing at all. We talk about why comedians are professional observers, why space makes us feel small in a good way, whether intelligent life is out there, why aliens probably have not visited Earth, and why the distances between stars and galaxies are so hard to overcome.

The conversation also covers dinosaurs, mass extinctions, water worlds, Mars, Venus, Saturn, the Moon, natural disasters, whether Tony would go to space, and why humans may be the biggest threat to life on Earth.

The Space Traders by Derrick Bell pdf: https://blog.richmond.edu/criticalracetheory/files/2019/02/The-Chronicle-of-the-Space-Traders.pdf

Derrick Bell was a civil rights lawyer and the first Black tenured professor at Harvard Law School. In his 1992 story The Space Traders, extraterrestrial visitors offer the United States enough gold and technology to erase its debt, restore the environment, and provide practically unlimited clean energy. Their price is every Black person in America.

In this episode, expect to learn how Bell imagines the offer moving through the president’s cabinet, Congress, corporate America, religious institutions, civil rights organizations, and a national vote. The story examines how political leaders can decide on an outcome first and then search the law for the precedent needed to defend it.

The conversation also covers tokenism, respectability politics, capitalism, public self-interest, the limits of legal equality, and whether the United States would make the same decision today. It ends with a larger science-fiction question: if aliens arrived, who would have the authority to speak for humanity?

In Part 3 of the Dr. Starkid astrobiology series, Dr. Dakotah Tyler traces the history of the universe from the Big Bang to the formation of worlds capable of supporting life.

Expect to learn about the three major lines of evidence for the Big Bang, Big Bang nucleosynthesis, the cosmic microwave background, the first stars, and how stellar explosions created the heavier elements needed to build planets.

The episode also covers planet formation, migrating gas giants, the Grand Tack model, why Mars may be so small, how Earth got some of its water, the giant impact that formed the Moon, and why icy moons such as Europa may contain oceans beneath their surfaces.

This series is adapted from astrobiology courses taught at UCLA and Pomona College.

Could an advanced civilization evolve on a planet where trees and wood never existed?

In this speculative astrobiology episode, Dr. Dakotah Tyler constructs a rocky super-Earth with stronger gravity, widespread volcanic activity, and immense crystal formations that function ecologically like forests. A six-limbed aquatic species gradually moves onto land and evolves the dexterity, spatial reasoning, memory, and problem-solving abilities needed to survive inside this dangerous three-dimensional environment.

Expect to learn why trees were so important to human evolution, why intelligent marine animals have not developed technological civilizations, and how evolution repurposes traits that originally evolved for survival. The imagined hexapods eventually learn to manipulate light, ignite fires without wood, excavate crystal cities, harness electrical properties, and develop advanced optics and astronomy.

This is not a prediction of what aliens must look like. It is a scientifically grounded world-building experiment exploring one plausible path to intelligence and civilization on a world very different from Earth.

Stars do much more than light up the universe. They create the environments where planets form, provide energy to those planets, manufacture new elements through fusion, and eventually return that material to the galaxy where another generation of stars, planets, and potentially life can form.

In this episode of the Dr. Starkid astrobiology series, Dr. Dakotah Tyler explains what happens inside stars, why quantum tunneling is necessary for fusion in the Sun, and why more massive stars actually live much shorter lives despite having more fuel.

The episode also explores the astrobiological consequences of stellar lifetimes, from red dwarfs that may survive for trillions of years to massive stars that can die before their planets have enough time to fully form.

Along the way, we visit the Cambrian explosion, some of the strangest organisms in Earth’s evolutionary history, the death of massive stars, and a supernova Dr. Dakotah Tyler personally observed during graduate school.

Ultimately, the elements inside planets and living things were produced by earlier generations of stars. The atoms inside your body existed before Earth, and some of them may continue their journey long after Earth is gone.

Arian Foster is a former NFL running back who played for the Houston Texans and Miami Dolphins. He also studied philosophy and, after reaching the NFL, developed a deep interest in science, physics, and some of the biggest questions about reality.

In this conversation, expect to hear Arian and Dr. Dakotah Tyler talk about general relativity, scientific expertise, misinformation, distrust of science, “doing your own research,” and why changing your mind when new evidence appears is a feature of science rather than a weakness.

The conversation eventually moves into the Big Bang, dark energy, the possible fate of the universe, the block universe, quantum field theory, consciousness, determinism, free will, God, religion, capitalism, democracy, human nature, and the strange stories humans build to hold societies together.

They also discuss Star Trek, the Borg, whether humans may eventually merge with artificial intelligence, why Arian strongly dislikes AI replacing human creativity, and what happens when people begin outsourcing their thinking to machines.
