James Webb Telescope Discovers Surprising Atmosphere on TRAPPIST-1 C Exoplanet

NASA's James Webb Space Telescope has discovered that TRAPPIST-1 c, a rocky exoplanet orbiting a red dwarf star, does not have a thick carbon dioxide atmosphere, making it unlikely to be a Venus analog. The planet, which has the coolest measured temperature for a rocky exoplanet, might have formed with minimal water content. It either lacks an atmosphere or possesses a very thin one, and further research will investigate temperature variations on the planet and continue studying potential atmospheric conditions.
