Researchers using the James Webb Space Telescope have discovered significant atmospheric differences on the tidally locked exoplanet WASP-39 b, revealing a hotter evening side compared to its morning side due to powerful atmospheric circulations. This study marks a milestone in understanding exoplanetary atmospheres, with implications for future research on other tidally locked hot Jupiters.
Researchers using the James Webb Space Telescope have confirmed that the exoplanet WASP-39 b, which is tidally locked to its star, exhibits significant atmospheric differences between its eternal morning and evening sides. The evening side is hotter by about 300°F (200°C) and less cloudy compared to the morning side. This discovery was made using Webb's NIRSpec, revealing detailed temperature and cloud cover variations, and providing new insights into the atmospheric dynamics of tidally locked exoplanets.
