- NASA’s Webb telescope discovers a planet where rock clouds vanish every night
NASA’s James Webb Space Telescope discovered a giant exoplanet, WASP-94A b, 700 light-years away, with a daily weather cycle where mineral clouds form in the morning and dissipate by night. The finding revealed the planet’s atmosphere is more Jupiter-like than previously thought.
- JWST maps the weather on a hot gas giant 700 light-years away
Using the James Webb Space Telescope, scientists discovered dynamic weather patterns on WASP-94A b, a hot gas giant 690 light-years away, finding it has cloudy mornings and clear evenings. This discovery suggests previous atmospheric models of exoplanets may have been oversimplified by averaging atmospheric conditions rather than accounting for dynamic weather systems.
