Jupiter’s third-largest moon Io is the most volcanically active world in our solar system. New radio images by the ALMA telescope array show the direct effect of this volcanic activity on the ...

The atmosphere of Io doesn't make it the sort of place you'd want to draw a deep breath. For one, it's incredibly thin, so nothing like a deep breath would even be possible.

At last, a decades-old mystery has been solved about the atmosphere on Jupiter’s volcano-riffic moon Io. This moon, whose super-lavalicious geological situation has earned it the titles “pizza ...

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 ...

A recent study of Io’s sulfurous atmosphere suggests that Jupiter’s moon has been a volcanic hellscape for almost the Solar System’s entire 4.57 billion-year history.

Any atoms that reach Io's upper atmosphere are at risk of being lost to space. And, because of their relative atomic weights, lighter isotopes have a higher probability of being lost.

Jupiter's moon Io is a volcanic hellscape—and has been since the solar system began. Io is the most volcanic body known to science, and researchers have puzzled over its history for years.

Measurements of sulphur isotopes in Io’s atmosphere show that the moon may have been volcanically active for its entire lifetime. Close. Advertisement. Skip to content. Sign in. Search the website.

Our moon may have once been as hellish as Jupiter's super volcanic moon Io; ... Nie and colleagues wanted to determine which process is primarily responsible for sustaining the moon's atmosphere.

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 ...

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.
