“Pink Planet” is surrounded by salty clouds, researchers using Webb telescope find
Astronomers using the James Webb Space Telescope have discovered an unusual “salt cloud” atmosphere on a distant object known as the Pink Planet (GJ504b). The object, located about 57 light-years from Earth, is a planetary-mass companion that could be either a giant exoplanet or a small brown dwarf. Researchers say its relatively cool temperature for a gas giant—about 550°F—likely allows salts to form clouds, a … Continue reading “Pink Planet” is surrounded by salty clouds, researchers using Webb telescope find
