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

A new volcano has been spotted on Jupiter's moon Io, the most geologically active place in the solar system. Analysis of the first close-up images of Io in over 25 years, captured by the JunoCam ...

"For the very first time, we have a global view of Io's ongoing volcanic activity." The most volcanically active world in the solar system, Jupiter's moon Io, may possess a global ocean of magma ...

There are hundreds of active volcanoes on Io. The new one is located just south of Io’s equator and the Juno images show fresh lava flows and volcanic deposits covering an area of 32,400 square ...

The close-ups showed a massive volcanic plume shooting from the moon’s surface, suggesting that Io wasn’t as geologically dead as traditionally thought. Some scientists at the time were already ...

And just like we have ocean tides on Earth, Io has tides of rock ... the Keck telescope in Hawaii (only 35 miles from the active volcano Kilauea) witnessed the most powerful volcanic eruption ...

While our moon is relatively calm, Io is considered to be the most volcanically active world in our solar system. And while Earth, of course, has plenty of active volcanoes of its own, eruptions ...

A new map of Jupiter's oddly active moon Io has revealed the location of the moon's many erupting volcanoes, raising as many questions about the enigmatic satellite as it answers. The map is the ...

Five worlds in the solar system have active volcanoes (those that are currently erupting or have erupted in human history): Earth, Jupiter’s moons Io and Europa, Neptune’s moon Triton ...

"Io represented a big mystery because its surface doesn't hold a record of its history the way that the surfaces of less active moons do." The solar system's most volcanic body, the Jupiter moon ...

The scientists detected 266 active volcanic hotspots on Io. They found the number of volcanoes scattered across the poles is about the same as that elsewhere on Io, but the polar volcanoes emit ...
