James Webb’s “Better Than Earth” Planet, The James Webb Signal Explained

James Webb looked at the exoplanet K2 18 b and found a chemical story that set the world on fire. Reports from April 17, 2025 described possible traces of sulfur compounds such as dimethyl sulfide and dimethyl disulfide, molecules linked on Earth to ocean microbes, and the planet may be a Hycean type world with a deep global ocean under a hydrogen rich atmosphere. But the scientific community is divided, and later NASA led analyses and broader spectrum studies have pushed back, saying the evidence is not yet conclusive. In this episode we break down how Webb reads an atmosphere from starlight, what was actually detected, why the signal is exciting, and why it is still not proof of life.
