The True Shape of Io's Steeple Mountain (weareinquisitive.com)

A science-content team says popular artwork of Io’s “Steeple Mountain” (Dis Mons) has its height and steepness overstated, largely due to misleading shadows from the mountain’s position near the day-night terminator in Juno photos. Using a Juno-based global map and the geometry of the observed shadow, they reconstruct an alternative, scaled appearance closer to estimates of the feature’s roughly 7 km height. The article also describes how Io’s volcanic heating from tidal forces and deep faulting tectonics shape mountains like Dis Mons.
