  • Magnetic field measurements made near Jupiter’s moon Io strengthen the evidence for a magma ocean in its interior. Extensive volcanism and high-temperature lavas hint at a global magma reservoir in Io, but no direct evidence has been available. We exploited Jupiter’s rotating magnetic field as a sounding signal and show that the magnetometer data collected by the Galileo spacecraft near Io provide evidence of electromagnetic induction from a global conducting layer. We demonstrate that a… CONTINUE READING
