Could a planet 124 light-years away hide oceans—and maybe life—under a thick hydrogen atmosphere? K2-18b is shaking up exoplanet science, with JWST detecting methane and carbon dioxide in its skies. But water? Not so much.Dive in as we explore:

• What makes Hycean worlds unlike anything in our solar system
• Why K2-18b’s atmosphere has scientists scratching their heads
• The harsh realities of greenhouse gases and tidal heating for habitability

Join us on this cosmic deep dive—are we staring at alien oceans, or just another mini-Neptune?#Exoplanets #HyceanWorlds #K218b #JWST #Astrobiology
