Jupiter ’s moon Io is a hotbed of geologic activity , with over 400 active volcanoes . Because of this high level of activity , scientist have been debate for years about what ’s going on under the moon ’s Earth’s surface . Now we have a go at it .
Below a abject - density gall of about 30 km lies a seething ocean of magma at least 50 km deep ( about 31 Swedish mile ) , which explains the constant volcanic detonation that make this lunation the most geologically fighting body in the solar system .
As a percentage point of comparing , the deepest part of Earth ’s ocean is 6.77 statute mile , at the foot of the Mariana Trench .
research worker at UCLA and UC Santa Cruz stick this out using existing data from the Galileo investigation . Recent find in the world of minerals have uncover that certain types of volcanic rocks can gestate an incredible electrical stream when molten . wait at the physique of Jupiter ’s magnetic subject assemble from Galileo , they surmise that warps in that field must have been due to an tremendous magma sea beneath Io ’s surface .
Short of sending a investigation to the moon ’s aerofoil , this is the closest glance we ’ll get at this distant and explosive lunar month .
