Jupiter's Magnetic Tornadoes: Unraveling Polar Mysteries

Astronomers from UC Berkeley have discovered large, Earth-sized dark ovals at Jupiter's poles, visible only in ultraviolet light, which are thought to be caused by magnetically driven vortices. These ovals, embedded in stratospheric haze, appear more frequently at the south pole and are linked to Jupiter's strong magnetic field. The study, using data from NASA's Hubble Space Telescope, suggests these features are formed by vortex dynamics rather than chemical reactions, offering insights into the atmospheric dynamics of giant planets.
