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… 
Io's Tortured Interior
Magnetic measurements made by the Galileo spacecraft reveal an ocean of magma under Io's frozen surface. Jupiter's moon Io is the most volcanic object in the solar system, injecting about a metric
A test for Io's magma ocean: Modeling tidal dissipation with a partially molten mantle: IO DISSIPATION
Magnetic induction measurements and astrometry provide constraints on the internal structure of Io, a volcanically active moon of Jupiter. We model the tidal response of a partially molten Io using
TIDAL HEATING IN A MAGMA OCEAN WITHIN JUPITER’S MOON Io
Active volcanism observed on Io is thought to be driven by the temporally periodic, spatially differential projection of Jupiter's gravitational field over the moon. Previous theoretical estimates of
The Librations, Tides, and Interior Structure of Io
The melt zone in the volcanically active satellite Io plays a key role in diverse processes such as volcanism, heat transfer, tidal dissipation, and the orbital evolution of the Galilean satellites
Magnetic Anomalies on Io and Their Relationship to the Spatial Distribution of Volcanic Centers
Abstract Forward modeling of planetary-scale magnetic anomalies due to induced crustal magnetization of Io is developed. The approach involves finite difference modeling of a temporally- and
Electromagnetic induction heating as a driver of volcanic activity on massive rocky planets
Aims. We investigate possible driving mechanisms of volcanic activity on rocky super-Earths with masses exceeding 3-4 Mearth. Due to high gravity and pressures in the mantles of these planets,
In Search of Subsurface Oceans within the Uranian Moons
The Galileo mission to Jupiter discovered magnetic signatures associated with hidden sub-surface oceans at the moons Europa and Callisto using the phenomenon of magnetic induction. These induced
Mountain building on Io driven by deep faulting
The high relief on Jupiter’s moon Io has been linked to compression due to global subsidence. Simulations show that Io’s mountains may form along thrust faults that initiate at the lithosphere’s base
Powering the Galilean Satellites with Moon‐Moon Tides
There is compelling evidence for subsurface water oceans among the three outer Galilean satellites, and evidence for an internal magma ocean in the innermost moon, Io. Tidal forces from Jupiter
Magma ascent pathways associated with large mountains on Io
Abstract While Jupiter's moon Io is the most volcanically active body in the Solar System, the largest mountains seen on Io are created by tectonic forces rather than volcanic construction. Pervasive

▪ Abstract Io, innermost of Jupiter's large moons, is one of the most unusual objects in the Solar System. Tidal heating of the interior produces a global heat flux 40 times the terrestrial value,
Subsurface Oceans on Europa and Callisto: Constraints from Galileo Magnetometer Observations
Magnetic field perturbations measured during Galileo flybys of Europa and Callisto are consistent with dipole fields induced by the temporal variations of the ambient jovian magnetospheric field.
Induced magnetic fields as evidence for subsurface oceans in Europa and Callisto
TLDR
P perturbations of the external magnetic fields (associated with Jupiter's inner magnetosphere) in the vicinity of both Europa and Callisto are reported, and it is argued that these conducting layers may best be explained by the presence of salty liquid-water oceans.
