James Webb Telescope Reveals Cause of Saturn's Apparent Rotation Rate Changes

Scientists have utilized observations from the James Webb Space Telescope to resolve a long-standing mystery regarding Saturn's seemingly variable rotation rate. The research indicates that powerful winds in the planet's upper atmosphere, driven by auroral heating, create electrical currents that sustain the aurora. This discovery, detailed in the *Journal of Geophysical Research: Space Physics*, clarifies that the planet's spin itself is not changing, but rather atmospheric dynamics are at play, offering insights into the interplay between Saturn's atmosphere and magnetosphere.
