Jupiter's Great Blue Spot: Unraveling the Mysterious Fluctuations in its Deep Interior

Scientists are puzzled by the fluctuating behavior of a tiny jet buried deep in Jupiter's atmosphere, which appears to fluctuate every four years. This jet is part of the intense magnetic field near Jupiter's equator, known as the "Great Blue Spot." New findings from NASA's Juno probe suggest wave-like behavior deep inside Jupiter's metallic core may power the observed magnetic field. The jet's fluctuation rate is fluctuating, and more observations from Juno could provide certainty and help scientists better understand the complex dynamo that powers Jupiter's magnetic field.
