James Webb Space Telescope finds first evidence of CO2 in exoplanet atmosphere
NASA is reporting another James Webb Space Telescope first as the orbital observatory has found clear evidence for carbon dioxide in the atmosphere of an exoplanet.-rich WASP-39b by the Hubble and Spitzer telescopes were able to detect water vapor, sodium, and potassium in the planet's atmosphere.
The discovery utilized JWST's Near-infrared Spectrograph to capture data on the brightness of the light passing through 39b's atmosphere as it orbits its star. Because different gasses absorb different wavelengths of light, the Webb team was able to look at changes in 39b's light absorption to determine what the atmosphere is made of.
Located some 700 light-years from Earth and orbiting its star at just an eighth of the distance between the Sun and Mercury, WASP-39b is an ideal target for this sort of observation, NASA said. Orbiting so close to its star means 39b has a transit time of just over four days, meaning researchers can get quick results from transmission spectroscopy, the process used to find its atmospheric CO
