Researchers based on the observations of the NASA "Juno" Jupiter probe. Study found changes in the magnetic field above Jupiter's "Great Blue Spot" Changes in Jupiter's magnetic field have been observed before and attributed to an equatorial jet.
Details of this jet have never been determined, and such details are crucial to understanding the dynamics of Jupiter's interior. The authors of the paper concluded that the detailed information provided by their latest research can help understand the previously unknown internal dynamic environment of Jupiter.
