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?

NASA’s Juno mission found Io’s biggest volcanic eruption ever. The explosion was stronger than all Earth’s power plants combined.

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.

NASA’s Juno mission has captured the most powerful volcanic eruption ever recorded on Io, Jupiter’s highly active moon. Even by Io’s extreme standards—where more than 400 volcanoes constantly reshape its surface—the latest event stands out as an unparalleled display of cosmic firepower.
