JWST Detects Significant Atmospheric Variations on Exoplanet WASP-121 b

The James Webb Space Telescope has observed notable atmospheric disparities between the dawn and dusk sides of the extremely hot exoplanet WASP-121 b. Intense winds transport heat from the permanent dayside, resulting in a hotter and more expanded evening side. Researchers also identified evidence of water dissociation due to extreme temperatures and the presence of enigmatic mineral clouds in the cooler atmospheric regions.
