JWST uncovers salty clouds on the cold Pink Planet GJ504b
TL;DR
Using the James Webb Space Telescope, astronomers detected salt clouds in the atmosphere of GJ504b, a cold, planetary‑mass companion orbiting a Sun‑like star about 57 light‑years away. With a mass around 25 Jupiter masses and an age of roughly 2.5–4 billion years, the object may be a planet or a brown dwarf, and the salty clouds help explain its atmospheric spectrum and raise questions about its origin.
