Io, one of the most fascinating moons in our solar system, continues to mystify scientists with its intense volcanic activity and bizarre behavior. This moon, known for its towering volcanoes, ...

The result may have been comparable to Jupiter's moon Io, the most volcanic body in the solar system. Early in the history of the solar system, a massive protoplanet plowed into a young Earth.

Because Io is so close to its massive host planet, the moon is subjected to a tremendous gravitational pull as it orbits Jupiter once about every 42 hours, according to the Planetary Society.

One of the big surprises: Despite the moon's cooled crust, the data shows Io maintains liquid hot lava just below the ground. In fact, about 10 percent of the surface has lava underneath it.

Scott Bolton’s first encounter with Io took place in the summer of 1980, right after he graduated from college and started a job at NASA. The Voyager 1 spacecraft had flown past this moon of Jupiter, ...
