Webb Rules Out Thick Carbon Dioxide Atmosphere for Rocky Exoplanet
NASA's James Webb Space Telescope measures heat energy from exoplanet TRAPPIST-1 c, hinting at an extremely thin atmosphere. This Venus-like planet's cool temperature challenges assumptions about rocky exoplanets' atmospheres, shedding light on the potential habitability of planets orbiting red dwarfs.
