Nature Astronomy, Published online: 10 July 2024; doi:10.1038/s41550-024-02292-x A combined analysis of datasets across four JWST instrument modes provides a benchmark transmission spectrum for the Saturn-mass WASP-39 b. The broad wavelength range and high resolution constrain orbital and stellar parameters

Nature Astronomy, Published online: 08 July 2024; doi:10.1038/s41550-024-02319-3 Centaur 29P/Schwassmann–Wachmann 1 exhibits a fascinating outgassing pattern in JWST observations, with compositional heterogeneities that may be related to the bilobate nature of its nucleus. The detection of CO and CO2 isotopologues
