Fifty-seven light-years from Earth, a cold and faintly glowing world known as the Pink Planet has finally yielded one of its secrets. Using the James Webb Space Telescope, astronomers at Northwestern University have detected salt clouds in the atmosphere of GJ504b — a phenomenon long theorized but never before observed. The discovery arrives after more than a decade of frustrated attempts with ground-based instruments, and it speaks to a quiet truth in science: some worlds only reveal themselves when we build the eyes worthy of seeing them.
