What’s Really Going On Inside Jupiter? New Models Offer Clues

Universe Today - Wed, 01/28/2026 - 11:04pm

Jupiter’s atmosphere and clouds have mesmerized stargazers for centuries, as their multi-colored, swirling layers can easily be viewed from powerful telescopes on Earth. However, NASA’s Juno spacecraft has upped the ante regarding our understanding of Jupiter’s atmospheric features, having revealed them in breathtaking detail. This includes images of massive lightning storms, clouds swallowing clouds, polar vortices, and powerful jet streams. Yet, despite its beauty and wonder, scientists are still puzzled about the processes occurring deep inside Jupiter’s atmosphere that result in these incredible features.
