Information about clouds, first data about photochemistry, and a near-complete chemical inventory that hints at the planet's formation history – those are some highlights from the recently published observations of the exoplanet WASP-39b with the James Webb Telescope (JWST).Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm).Photochemistry is even more important on cooler planets that may be habitable – the ozone layer on our own planet is formed via a photochemical process.
