This graphic shows the transmission spectrum obtained by Webb observations ... that the signal could be from a water-rich planetary atmosphere (indicated by the blue line) or from starspots ...
We then obtained the transmission spectrum of the atmosphere of the exoplanet from these observations. This spectrum hinted at the possible presence of an atmosphere filled with sulfur dioxide and ...
A broad-wavelength 0.5–5.5 µm atmospheric transmission spectrum of WASP-39b, a 1,200 K, roughly Saturn-mass, Jupiter-radius exoplanet, demonstrates JWST’s sensitivity to a rich diversity ...
