Webb Telescope Unveils Atmospheric Differences on Distant Exoplanet

New findings highlight temperature and cloud cover variations between the perpetual morning and evening sides of WASP-39b.

WASP-39b, a tidally locked exoplanet, shows significant temperature differences between its morning and evening sides.
The James Webb Space Telescope's sensitivity enabled the detection of these variations, with the evening side being hotter by 300 degrees Fahrenheit.
Researchers used transmission spectra to analyze the exoplanet's atmosphere, revealing distinct cloud cover patterns.
High-speed winds circulate around the planet, contributing to the temperature and atmospheric differences.
The study marks a significant advancement in understanding atmospheric dynamics on exoplanets and sets the stage for future research.
