New theory proposes Jovian magnetosphere circulates magnetic field remarkably different from that of Earth

Space physicists have long assumed that the magnetosphere at Jupiter circulates that planet's magnetic field in the same way as Earth. At Earth, this circulation drives the aurora and the magnetic storms that cause space weather. Researchers from Southwest Research Institute and the University of Colorado at Boulder have developed a new model that postulates the structure and magnetospheric processes at Jupiter are significantly different from those at Earth.
