Io, one of Jupiter’s Jovian moons, is the most volcanic place in our entire Solar System. Over the last few years NASA’s Juno ...

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.

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 ...

A NASA spacecraft made its closest-ever approach to Jupiter's moon Io, coming within 930 miles of the "surface of the most volcanic world," and the space agency released new images of the flyby.

Jupiter moon of Io is famed for its volcanoes. NASA just spotted the most powerful one yet Not only was the hot spot larger than Earth’s Lake Superior, but it also was seen belching out ...

Jupiter's moon Io is the solar system's most volcanic body thanks to a gravitational tug of war that rages below its surface. But now scientists know the violent moon has always been this way.

No moon in our solar system is likely as chaotic as Io, Jupiter’s third largest. The rocky body looks like a pepperoni pizza because of the constant, numerous eruptions on its surface.

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 ...

Data from previous missions had made planetary scientists wonder whether, rather than just pockets of melt, Io contained a 31-mile (50-kilometer) deep layer of magma: a moon-wide ocean of molten rock.

NASA orbiter spots most active volcano yet on Io The third and latest flyby, which took place on Dec. 27, 2024, brought the Juno spacecraft within about 46,200 miles of the moon.
