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

NASA's Juno spacecraft has spotted the most powerful volcanic eruption ever seen on the solar system's most volcanic body, the Jovian moon Io.

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 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.
