The James Webb Space Telescope has allowed astronomers to observe a unique phenomenon on a planet outside our solar system: the formation and disappearance of clouds on its night side. The planet in question, WASP-94 A b, is located approximately 690 light-years from Earth and belongs to the category of "hot Jupiters," gas giants extremely close to their star.
Researchers have observed that clouds form on the side of the planet plunged into permanent darkness, where temperatures are slightly less extreme. Conversely, when atmospheric winds carry these cloud formations toward the side facing its star, they quickly disappear under the intense heat.
A major breakthrough in the study of exoplanets
This observation represents a significant step in understanding extraterrestrial climates. Thanks to the infrared capabilities of the James Webb Space Telescope, scientists can now analyze with greater precision the composition and atmospheric dynamics of worlds very far from Earth.
According to researchers cited in the journal Nature, the strong winds sweeping across WASP-94 A b continuously shift cloud masses between the planet's two hemispheres. This work paves the way for future observations of exoplanets potentially closer to Earth's conditions and likely to one day harbor environments conducive to life.
