Variations in the magnetic field at Jupiter’s so-called "Great Blue Spot" - a region of intense magnetic field along its equator first spotted in observations from NASA’s Juno spacecraft - are reported in a new study just published in Nature. This analysis may provide insights into the gas giant’s interior.

A rapidly time-varying equatorial jet in Jupiter’s deep interior - Nature
An axisymmetric, equatorial jet in Jupiter’s interior has a wavelike fluctuation with a 4-year period, revealing hidden aspects of the magnetic field within the metallic hydrogen region and constraining the dynamo that generates the magnetic field.
