Astronomers at The Johns Hopkins University, the Observatoire de Paris, and other institutions have solved a nearly 30-year-old mystery surrounding Jupiter’s moon Io, showing that volcanoes there ...

A study utilizing ALMA observations of Io's atmosphere reveals a significant depletion of lighter sulfur isotopes, suggesting extensive and prolonged volcanic activity throughout its 4.57 billion-year ...

A 4-billion-year-old volcano? New research finds that Io, the solar system’s most volcanically active moon, can brag just that. A recent study of Io’s sulfurous atmosphere suggests that Jupiter’s moon ...

The atmosphere on Jupiter’s moon Io is a witches’ brew, composed primarily of the sulfurous exhalations of more than 400 volcanoes that dot the surface. Until now, however, it has been unclear whether ...

NASA's Juno spacecraft has made a second flyby of Jupiter's moon Io, capturing the solar system's most volcanic body in stunning detail. The spacecraft also allowed operators to glimpse a side of Io ...

Jupiter’s moon Io has been continuously remodelled by volcanic eruptions for billions of years, possibly since it first formed. Io is the most volcanically active body in the solar system, spewing ...

Jupiter’s moon Io has been continuously shaped by volcanic activity for billions of years — possibly even for the Solar System’s entire 4.57-billion-year history, a study suggests. The findings, ...

Jupiter’s moon Io has possibly been erupting for a very, very, very long time. Io is the most volcanically active body in our solar system, with some of its volcanoes shooting magma higher than planes ...

The last time a spacecraft got this close to Jupiter’s moon Io was more than 20 years ago, a blink of an eye on a typical geological timescale. Most planetary bodies in our Solar System wouldn’t ...

NASA's Juno mission has made its 51st close flyby of Jupiter, catching stunning images of its moon Io, in the process. Juno flew past Io on Tuesday, May 16, on a flyby that brought it closer to the ...
