James Webb reveals two completely different twilights on an alien world
The James Webb Space Telescope has observed significant temperature and atmospheric differences between the dawn and dusk sides of the ultra-hot exoplanet WASP-121 b. The evening side is hotter and has a more expanded atmosphere due to winds carrying heat from the permanently sunlit day side. The findings also suggest that water molecules are breaking apart in the hotter regions, while mineral clouds may be influencing the cooler night side. This discovery provides new insights into atmospheric dynamics on exoplanets.
The James Webb Space Telescope found that the morning and evening sides of the exoplanet WASP-121 b have very different temperatures and atmospheres.
This discovery helps scientists understand how extreme heat and winds shape the atmospheres of planets far from Earth, improving models of exoplanet climates.
It shows how advanced technology can reveal hidden details of distant worlds, inspiring curiosity and expanding our knowledge of the universe.
