Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a
fundamental step towards constraining the dominant chemical processes at work and, if in …

The search for habitable environments and biomarkers in exoplanetary atmospheres is the
holy grail of exoplanet science. The detection of atmospheric signatures of habitable Earth …

The field of exoplanet atmospheric characterization has recently made considerable
advances with the advent of high-resolution spectroscopy from large ground-based …

The ExoMol database (www. exomol. com) provides molecular data for spectroscopic
studies of hot atmospheres. These data are widely used to model atmospheres of …

Close-in giant exoplanets with temperatures greater than 2,000 K ('ultra-hot Jupiters') have
been the subject of extensive efforts to determine their atmospheric properties using thermal …

This review presents an insight into our current knowledge of the atmospheres of the planets
Venus, Mars, Jupiter, Saturn, Uranus and Neptune, the satellite Titan, and those of …

The recent inference of sulfur dioxide (SO2) in the atmosphere of the hot (approximately
1,100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations …

We present the dayside thermal emission spectrum of WASP-77Ab from 2.8 to 5.2 μm as
observed with the NIRSpec instrument on the James Webb Space Telescope (JWST) …

The future is now–after its long-awaited launch in 2021 December, JWST began science
operations in 2022 July and is already revolutionizing exoplanet astronomy. The Early …

The JWST has ushered in a new era in atmospheric characterisations of temperate low-
mass exoplanets with recent detections of carbon-bearing molecules in the candidate …
