  • Spectroscopic observations of the ultra-hot Jupiter WASP-189b reveal both volatile (H2O, CO, OH) and refractory (Fe, Mg, Si) gas in its atmosphere. Here, the authors show that the abundance ratio of refractory species reflects that of the host star.

  • Precise mass and radius measurements of giant planet WASP-193 b find an extremely low density of 0.059 ± 0.014 g cm−3. Current evolutionary models cannot fully explain such a low density, but the extended atmosphere makes WASP-193 b very suitable for high-precision characterization via JWST.

  • Absorption lines of iron in the dayside atmosphere of an ultrahot giant exoplanet disappear after travelling across the nightside, showing that the iron has condensed during its travel.

  • Autotransporter proteins are localised to the bacterial surface and promote colonisation of host epithelial surfaces. Here, the authors present the crystal structure of autotransporter UpaB and show evidence for distinct binding sites for glycosaminoglycans and host fibronectin.

  • Observations of TOI-849b reveal a radius smaller than Neptune’s but a large mass of about 40 Earth masses, indicating that the planet is the remnant core of a gas giant.

  • The transmission spectrum of the exoplanet WASP-39b is obtained using observations from the Single-Object Slitless Spectroscopy mode of the Near Infrared Imager and Slitless Spectrograph instrument aboard the JWST.

  • Observations of six transiting planets around the bright nearby star HD 110067 show that they follow a chain of resonant orbits, with three of the planets inferring the presence of large hydrogen-dominated atmospheres.

  • Phase-resolved mid-infrared observations from JWST of the hot gas giant WASP-43b detect a day–night difference of 659 ± 19 K. Comparison with climate models shows that the observations are compatible with cloudy skies, at least on the nightside, and the lack of methane detection suggests the presence of disequilibrium chemistry.

  • The medium-resolution transmission spectrum of the exoplanet WASP-39b, described using observations from the Near Infrared Spectrograph G395H grating aboard JWST, shows significant absorption from CO2 and H2O and detection of SO2.

  • Time-series observations from the JWST of the transiting exoplanet WASP-39b show gaseous water in the planet’s atmosphere and place an upper limit on the abundance of methane.

  • The dayside thermal emission spectrum and brightness temperature map of the ultra-hot Jupiter WASP-18b obtained from the NIRISS instrument on the JWST showed water emission features, an atmosphere consistent with solar metallicity, as well as a steep and symmetrical decrease in temperature towards the nightside.

  • Observations from the JWST show the presence of a spectral absorption feature at 4.05 μm arising from SO2 in the atmosphere of the gas giant exoplanet WASP-39b, which is produced by photochemical processes and verified by numerical models.

  • A broad-wavelength 0.5–5.5 µm atmospheric transmission spectrum of WASP-39b, a 1,200 K, roughly Saturn-mass, Jupiter-radius exoplanet, demonstrates JWST’s sensitivity to a rich diversity of exoplanet compositions and chemical processes.

  • Three planets orbit the Sun-like star ν2 Lupi. CHEOPS data show that all of them are transiting and show remarkable diversity. In particular, dry and gas-poor inner planet b has experienced extensive atmospheric loss, while planets c and d are water rich and have a small gaseous envelope of primordial origin.
