Jupiter’s auroras arise from a magnetic ‘tug-of-war’ with volcanic eruptions on its moon Io

Jupiter’s auroras are caused by a cosmic game of “tug-of-war,” fueled by volcanoes on the planet’s innermost moon, Io, new research suggests. 

NASA’s Juno spacecraft and Hubble Space Telescope have revealed new evidence suggesting Jupiter’s rapid rotation and the release of sulfur and oxygen from volcanoes on Io — the most volcanically active world in the solar system — create an electric current system that drives the powerful auroras observed around the gas giant’s poles, according to a statement from the University of Leicester.
