  • The thermal emission spectrum of the rocky exoplanet 55 Cancri e obtained by the NIRCAM and MIRI instruments aboard the JWST indicates that it has a secondary volatile-rich atmosphere, possibly arising from a magma ocean.

  • Observations from the JWST MIRI/LRS show the detection of SO2 spectral features in the 5–12-μm transmission spectrum of the hot, Saturn-mass exoplanet WASP-39b, suggesting that photochemistry is a key process in high-temperature exoplanet atmospheres.

  • 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.
