Could Earth Life Survive on Enceladus? Inside the Alien Ocean Experiment

2026-09-2930:14

Could something alive on Earth survive in the ocean beneath an alien moon’s ice? Researchers tested that question by recreating some of the conditions thought to exist on Enceladus, a small moon of Saturn. The archaea they introduced survived and multiplied under some of those simulated conditions. I wanted to understand how you even design that experiment when the ocean you’re studying is buried beneath ice. We talk through Cassini’s encounters with Enceladus’s plumes, how tidal heating keep...

How Fast Can a Planet Form? The Youngest Planet Ever Discovered

2026-09-2446:42

Elias 2-24b is already several times Jupiter’s mass, yet its star system is estimated to be less than a million years old. This episode follows the discovery and asks how a gas giant can grow so massive, so quickly. We cover how astronomers use infrared and radio observations to study young planets, how they estimate ages, and why growing from tiny grains into a giant planet is a bit more complicated than it sounds. We also look at how an early forming giant planet can influence the fut...

Life on Earth Might Have Started on Mars

2026-09-0401:37:56

You might be a Martian. In this installment of the Dr. Starkid astrobiology series, I’m making the case that life on Earth may have actually started on Mars first. This idea does not yet have scientific consensus, but there is a convincing evidence-based argument for what might be the simplest explanation for why life showed up on Earth so early. Expect to learn about panspermia, LUCA, the origin of life, why Mars may have been chemically ready for life before Earth, how early Earth may hav...

Physics Is At Play In Your Personal Life

2026-08-2157:29

Momentum is a basic concept in physics: mass in motion, moving in a particular direction. But it also provides an interesting way to think about how a human life takes shape. In this episode, Dr. Dakotah Tyler starts with the physics of momentum, inertia, conservation laws, and the strange rotations of planets like Uranus and Venus. From there, the conversation moves into biology, energy efficiency, the high metabolic cost of the human brain, learning, automaticity, and why repeated behaviors...
