Moons leave their mark on Jupiter’s aurora
I’ve just written a story for ABC Science about astronomers confirming that Ganymede’s journey around Jupiter causes spots to appear in the giant planet’s spectacular electric blue auroral lights.
The discovery, confirms the footprints are caused by Jupiter’s moons passing through plasma of particles in the planet’s magnetic bubble or magnetosphere.
The particles are generated by eruptions on Jupiter’s volcanic moon Io.
