Did JWST Find an Ocean World? K2-18b Explained.

Dive into K2-18b — the intriguing sub-Neptune that might be a Hycean ocean world. In this 12-minute deep-dive we unpack JWST’s detections of carbon dioxide and methane, what those gases mean for habitability, how a hydrogen-rich atmosphere and global ocean could support life, and the challenges of distinguishing biosignatures from abiotic chemistry. Perfect for fans of exoplanets, astrobiology, and space exploration, this video explains current evidence, modeling limits, and next steps in the search for life beyond Earth.
