Jupiter’s moon Io may have been volcanically active throughout its life. In this image of Io, taken by NASA’s Juno spacecraft in 2023, a bright volcanic plume can be seen on the left, just ...

These composite views depicting volcanic activity on Io were generated using both visible light and infrared data collected by NASA's Juno spacecraft during flybys of the Jovian moon on Dec. 14 ...

After making the closest Io flyby of any spacecraft in more than 20 years, NASA's Juno probe returned amazingly detailed imagery that will help scientists discover the source of the small moon's ...

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.

Assuming Io initially held some 20,000,000,000,000,000,000,000 (or 20 sextillion) tons of sulfur, the amount it’s lost so far leaves roughly 200 quintillion to 1.2 sextillion tons of sulfur ...

Io, the innermost of Jupiter's four largest moons, is slightly bigger than Earth's moon. Io is the most volcanically active body in the solar system, bursting with plumes that rise up to more than ...

But the moon’s wild volcanic activity wasn’t detected until Voyager 1 flew by Jupiter and its moons in 1979, revealing Io’s dynamic surface that resembled a pepperoni pizza, Bolton said.

Behold the volcano-blanketed moon, Io. After swooping by Jupiter's tortured moon on Feb. 3, NASA 's Juno spacecraft beamed back some of the closest-ever images of this unique world.

Moon-quakes first measured by the Apollo astronauts have been attributed to these tides. The tides that Jupiter raises on Io, however are powerful enough to induce sufficient friction in that moon ...

NASA's Juno spacecraft will come closer to Jupiter's moon Io on Dec. 30 than any spacecraft has in 20 years, getting a good look at the solar system's most volcanic body.
