Infrared spectra from the James Webb Space Telescope reveal hydrogen sulfide in the atmosphere of HR 8799 c, a gas giant five to ten times the mass of Jupiter, indicating it likely assembled a solid core before accreting gas. This chemical fingerprint implies that core accretion can operate at much higher masses than previously thought, forcing a reassessment of the empirical split between massive planets and brown dwarfs.
