These pressures are accessible by planar shock and ramp-loading experiments at large laser facilities. The central pressure in CoRoT-7b is probably close to 0.8 TPa, though may be up to 2 TPa.

Planetary transmission spectra taken in 2022 has indicated the atmosphere of WASP-39b is partially cloudy, and planet C/O ratio appears to be subsolar. WASP-39b is the first exoplanet in which carbon dioxide has been detected. Sulfur dioxide was observed in this planet's atmosphere for the first time, or indeed of any planet outside of the Solar System, indicating the existence of photochemical processes in the atmosphere. WASP-39b is one of the James Webb Space Telescope's early release science targets. High-fidelity spectra obtained by the James Webb Space Telescope in 2022 did not confirm a disequilibrium chemistry. The atmospheric transmission spectra, taken by different instruments, were inconsistent as in 2021, possibly indicating a disequilibrium atmospheric chemistry. Hot water molecules were found in the atmosphere of WASP-39b in a 2018 study. WASP-39b's atmospheric transmission spectrum captured by Webb’s Near-Infrared Spectrograph (NIRSpec) reveals first clear evidence for carbon dioxide in a planet outside the Solar System.
