  • The cool sub-Neptune LP 791-18 c, with an equilibrium temperature of 355 K, was found to host a hazy atmosphere, distinct from any other temperate sub-Neptune studied so far. The discovery demonstrates the intrinsic diversity of these worlds.

  • A complete revolution of exo-Neptune LTT 9779 b was observed with the NIRISS/SOSS instrument onboard the JWST. The resulting full phase curve is indicative of an equatorial jet that transports heat from the dayside to the colder nightside, resulting in an asymmetric distribution of clouds on the planet.

  • JWST observed helium and water in the atmosphere of the giant planet WASP-107 b, revealing a vast outflow of gas and evidence for recent inward migration. The findings shed light on how giant planets lose mass and evolve over time.

  • The JWST has the potential to increase our understanding of terrestrial exoplanets and their atmospheres, but the various signal contaminations need to be isolated and quantified. Using JWST Cycle 1 observations of TRAPPIST-1 as a benchmark, this Perspective proposes a series of steps to use future JWST data efficiently for this purpose.
