Famous “Pink Planet” harbors a salty surprise

Found in 2013, Pink Planet was too faint to study with ground-based telescopes. In new study, scientists used JWST and advanced processing methods to obtain its spectrum for the first time. Observations provided some of the first direct evidence for salt clouds in a cold object atmosphere. Pink Planet could be a giant planet or brown dwarf, so astronomers refer to it as a ‘planetary-mass companion’.
