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 ...

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.

We knew data from Juno’s two very close flybys could give us some insights on how this tortured moon actually worked.” Io orbits around Jupiter, the largest planet in our solar system ...

In 1979, NASA Jet Propulsion Laboratory (JPL) scientist Linda Morabito discovered volcanic activity on Jupiter’s innermost moon, Io. But Io isn’t just volcanically active—it is the most ...
