NASA's Juno spacecraft has discovered a giant volcanic hot spot on the surface of Jupiter's hellish moon Io. The eruptions in this area are chucking out six times the energy being produced by all ...

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.

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.

NASA engineers revived a radiation-damaged space camera on Juno using heat—just in time to capture stunning images of Jupiter ...

What color is moonlight typically, and what other colors can moonlight look like from our perspective on Earth?

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 ...

Using data collected by NASA's Juno spacecraft as it flew past Jupiter's highly volcanic moon Io in late 2023 and again in early 2024, a Southwest Research Institute-led team identified electrons ...

The energy for the volcanic activity comes from the squeezing and stretching of the moon by Jupiter’s gravity as Io orbits the largest planet in the solar system. Galileo was launched in 1989 and ...
