Webb detects carbon dioxide in exoplanet atmosphere
Paris (ESA) Aug 26, 2022
The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like star 700 light-years away. The result provides important insights into the composition and formation of the planet, and is indicative of Webb's ability to also detect and measure carbon dioxide in the thinner atmospheres of smaller rocky planets
