Webb detects carbon dioxide on an exoplanet #shorts

A transmission spectrum of the hot gas giant exoplanet WASP-39 b, captured by Webb’s Near-Infrared Spectrograph on 10 July 2022, reveals the first definitive evidence for carbon dioxide in the atmosphere of a planet outside the Solar System. This is the first detailed transmission spectrum ever captured that covers wavelengths between 3 and 5.5 microns.
