#34 - Where Did Earth's Oceans Come From? The Asteroid Theory is DEAD

Where did Earth's water come from? For decades, the Late Veneer hypothesis taught us that icy comets and asteroids delivered our oceans after the planet formed. But a groundbreaking January 2026 NASA study has completely rewritten the history books. By analyzing ancient Apollo lunar samples and measuring the Deuterium to Hydrogen ratio, scientists discovered that Earth's water was actually an inside job—baked directly into the planet's building blocks from the very beginning.In this deep dive, we explore the thermodynamic paradox of the solar system snow line, the secrets hidden inside enstatite chondrites, and what this massive shift in planetary science means for the search for alien life and the upcoming Artemis missions.If you love exploring the mysteries of the cosmos, make sure to like, subscribe, and drop a comment below on what you think this means for finding water on exoplanets!00:00 The Blue Marble Paradox: Why Earth Shouldn't Have Water05:15 The Snow Line and Solar System Thermodynamics Explained10:30 The Late Veneer Hypothesis: Did Comets Bring Our Oceans?15:45 NASA's 2026 Breakthrough: Analyzing Apollo Lunar Samples22:10 The Isotopic Fingerprint: Deuterium to Hydrogen Ratios27:30 Enstatite Chondrites and the "Inside Job" Water Theory32:00 Artemis Missions and the Future of Astrobiologyearth's water origin, late veneer hypothesis, nasa 2026 study, where did oceans come from, enstatite chondrites, carbonaceous chondrites, deuterium to hydrogen ratio, solar system formation, lunar samples apollo, astrobiology alien life, space science podcast, planetary formation, protoplanetary disk, early earth history, water on the moon, deep space mysteries, planetary science, origin of the oceans#SpaceScience #PlanetaryScience #NASA #Astrophysics #EarthsWater #Astronomy #Podcast
