The Pink Planet 57 Light-Years Away Has Clouds Made of Salt — And JWST Just Changed Everything We Thought We Knew About It
Scientists have theorised for 15 years that salt clouds might exist around cold planetary companions. They have never found direct evidence — until now. JWST observed GJ504b, the famous Pink Planet, for two hours. Ground-based telescopes had failed to obtain its spectrum after observing for entire nights. The result: a rich cocktail of water, carbon dioxide, methane, ammonia — and deep within the atmosphere, clouds of salt that nobody expected to actually find.
