Jupiter's moon Io may be small (roughly the size of Earth's moon) compared to the planet (more than 1,300 Earths could fit inside Jupiter), but the moon still has a mighty impact on its parent planet.

The exoplanet may be as volcanic as Jupiter's moon Io, which is very active due to the planet's gravitational forces heating up its interior.

Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system.

Although the ocean covers roughly 71% of Earth’s surface, more than 80% of that ocean has yet to be mapped, explored, or even ...

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.

NASA's Voyager 2 spacecraft made its closest approach to Jupiter. It came within 354,000 miles (570,000 kilometers) of the ...

Space is a very big place, and as such, it's full of mysteries that scientists can't explain. Some of this is simply because it's impossible to fully observe, thanks to its sheer size and the ...

Recent flybys of the fiery world refute a leading theory of its inner structure—and reveal how little is understood about geologically active moons.

But if Io doesn’t have a magma ocean, what might that mean for Europa? And, scientists now wonder, how does tidal heating even work? Melting Magma Heat drives geology, the rocky foundation upon which ...

NASA's Juno spacecraft has provided new insight about Jupiter's massive polar cyclones and what's going on beneath its volcanic moon Io.
