James Webb Telescope Discovers Distinct Twilights on Exoplanet WASP-121 b

11 Haziran 2026Science Daily

The James Webb Space Telescope (JWST) has uncovered significant variations between the dawn and dusk areas of the exoplanet WASP-121 b. The findings indicate that intense winds transport heat from the planet's always-lit side, resulting in a hotter and more expanded evening side.
Additionally, researchers observed that extreme temperatures are causing water to disintegrate and that enigmatic mineral clouds may influence the atmosphere on the cooler side.
WASP-121 b is a 'hot Jupiter' exoplanet located approximately 850 light-years from Earth. It is known for its extreme temperatures and unique atmospheric conditions, making it an intriguing subject for study.
The discoveries made by JWST highlight the complex atmospheric dynamics of exoplanets, particularly those with extreme conditions like WASP-121 b. The interaction between heat distribution and atmospheric composition raises questions about the potential for habitability and the formation of unique weather patterns i…
