Abstract: JWST started its science operations a year ago. Since then, there's been a large influx of atmospheric characterisation of exoplanets in the infrared, previously only partially accessible with high-resolution spectrographs or space telescopes such as Spitzer. Highlights of early JWST results include detections of carbon dioxide, the lack of detection of methane in some planets and the detection of sulphur dioxide, a product of photochemistry. The implications of these precise observations broad, from planet formation and migration history to challenging our atmospheric models.

In this talk I will give an overview of the first spectra of transiting exoplanets taken with JWST as part of the Transiting Exoplanet Community Early Release Science (TEC ERS) program, including the research I led. I will also show recent JWST observations that demonstrate its capabilities and the new insights we can gather about exoplanetary atmospheres, with a focus on transiting gas giants.

In addition to showing new, shiny JWST results, I will also take some time in this talk to discuss synergies between JWST and other telescopes and demonstrate that observations in the bluer wavelength ranges are also necessary to fully characterise an exoplanet's atmosphere.

In the final part of this talk, I will show a few examples of upcoming JWST exoplanetary science that I'm particularly excited about.
