A planet that tricks physics? Webb reveals the secret behind Saturn’s strange rotation

SMRTR summary

Saturn appeared to rotate at different speeds depending on measurement methods, baffling scientists for decades since planets shouldn't change rotation rates. Using the James Webb Space Telescope, researchers discovered Saturn's auroras create a self-sustaining cycle where auroral energy heats the atmosphere, drives winds that generate electrical currents, which then power more auroras, creating misleading rotation signals.
