Researchers find "Pink Planet" has salty clouds: "We were very surprised"

Astronomers using the James Webb Space Telescope found clouds made of salt on the so‑called "Pink Planet" (GJ504b) — a surprising first detection of salt clouds in a planetary atmosphere.
GJ504b orbits a star 57 light‑years away, is about 25 times Jupiter's mass and relatively cool (≈550°F), conditions that let salt clouds form instead of water, ammonia or silicate clouds.
Webb's infrared power made the discovery quick (a 2‑hour observation) and also revealed water vapor, methane, CO2 and ammonia — opening the door to studying even colder, unusual worlds.
