Io, Jupiter’s fiery moon, just erupted with enough energy to power Earth six times over! NASA’s Juno mission captured this mind-blowing event, revealing a hidden world beneath the surface. What does this mean for space exploration?

Jupiter’s moon Io is the most volcanically active world in the Solar System. The gravitational tug-of-war between Jupiter and its other large moons squeezes Io so that its interior is molten. That magma finds its way to the surface in lava lakes and volcanic eruptions.
