Fifty-seven light-years from Earth, a world long known but little understood has finally spoken. GJ504b — the Pink Planet — has held its chemical secrets for thirteen years, waiting for an instrument capable of listening at the right frequency. The James Webb Space Telescope, orbiting above the interference of our own atmosphere, translated the object's faint infrared glow into something remarkable: the first direct evidence of salt clouds suspended in the atmosphere of a cold planetary-mass companion. In doing so, it reminded us that the universe routinely outpaces our models, and that patien
