Surprising North-South Asymmetry in Jupiter’s Magnetic Field

Jupiter's magnetic field is more complex in the northern than southern hemisphere
• Current theoretical models have trouble explaining this asymmetry.
• This asymmetry is very different from Earth’s field.

Jupiter’s magnetic field is more complex in the northern hemisphere and its North-South asymmetry is likely due to interior structure

North-South asymmetry in Jupiter’s magnetic field likely due to the interior structure
• Potential evidence of core dissolution
• Helium rain and/or Jupiter’s electrical conductivity profile could also contribute to asymmetry
