Astronomers have made a surprising discovery about the upper atmosphere of Jupiter, turning previous beliefs on their head. The atmosphere of Jupiter has always been a source of fascination, with its ever-changing environment showcasing bands of different colors, storms, enormous clouds, and more. However, the upper atmosphere was thought to be uneventful, apart from the polar aurorae.
Recent observations by astronomers have revealed intricate structures above the iconic Great Red Spot on Jupiter. Using the James Webb Space Telescope (JWST), they discovered dark arcs and bright spots that are visible in infrared. These variations are not caused by sunlight, but by gravity waves originating from the turbulent lower atmosphere around the Great Red Spot.
Team leader Henrik Melin expressed his surprise, stating that the upper atmosphere of Jupiter is just as interesting as the northern lights, if not more so. The discovery was made as part of the Early Release Science program for JWST, shedding new light on this mysterious region.
This breakthrough will not only help astronomers better understand Jupiter’s upper atmosphere but will also aid in planned observations for the European Space Agency’s JUICE mission. The results of this study have been published in Nature Astronomy, marking a significant advancement in our knowledge of the gas giant’s atmosphere.
