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.

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

Juno is flying close to Jupiter tomorrow but it won’t be near Io. The next close pass of Io will happen on March 3, although the spacecraft will be further away from the Moon than it was last month.

The north polar region of Jupiter's volcanic moon Io was captured by the JunoCam imager aboard NASA's Juno during the ...

NASA has successfully restored a damaged camera aboard its Juno spacecraft orbiting Jupiter. The recovery of JunoCam, a ...

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 ...

That mission, which is slated to end in September 2025, also extends to Jupiter's rings and many moons. Juno’s trajectory passes by Io every other orbit, flying over the same part of the moon ...
