Saturn's Aurora Instigates a Bizarre Spinning Illusion, Driven by a Nonstop Cycle of Wind and Heat

By analyzing data from the James Webb Space Telescope (JWST), researchers have discovered that the complexity of Saturn's northern aurora patterns is fueled by a feedback loop caused by these auroraes themselves. This effect would explain in particular the differences observed in the measurements of the planet's speed of rotation, which would in fact be only the manifestations of winds in the upper atmosphere generating the electric currents fue…
NASA Shock: Saturn’s Rotation “Change” Was Just an Atmospheric Illusion
NASA Shock: Saturn’s Rotation “Change” Was Just an Atmospheric IllusionScientists thought Saturn was changing its rotation speed, but new James Webb Space Telescope observations reveal the planet’s aurora is creating a moving atmospheric system that mimics a shifting spin.

JWST just helped solve Saturn’s mysterious spin problem
For years, Saturn made no sense. Measure its rotation rate using radio signals from its aurora and you get one number. Use the planet’s gravity field and you get another. Worse still, the radio-derived rate appeared to be slowly changing over time, which is physically impossible for a planet. A world cannot simply speed up or slow down its spin. Now, using the most powerful space telescope ever built, researchers at Northumbria University have p…
