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.

The Juno mission has discovered remarkably strong activity on Jupiter's moon, Io. The hot spot emits eruptions with energy six times greater than the total power of all power plants in the world, NASA's Juno mission scientists caution.

The acid yellow moon Io that orbits Jupiter may be less than 30% the size of Earth, but is considered the most volcanic body in our solar system. As demonstrated by explosive news from NASA on Tuesday: Io’s southern hemisphere contains a hotspot of volcanic activity so massive, it is larger than Lake Superior.

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 been orbiting Jupiter for more than eight years, probing the solar system's largest planet with its suite of specialized instruments. The mission's extended mission has seen NASA turn its attention to Jupiter's moons,

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.
