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 ...

After zipping past the massive Ganymede in 2021 and the icy Europa in 2022, Juno executed its first close flyby of Jupiter’s volcanic moon Io, the innermost of the planet’s four large ...

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.

NASA's robotic Juno spacecraft is delivering the fresh data on Io with a series of flybys, each getting closer to Jupiter's volcanic moon until a pair of close-up encounters at a range of less ...

Io, one of the most fascinating moons in our solar system, continues to mystify scientists with its intense volcanic activity and bizarre behavior. This moon, known for its towering volcanoes, ...

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 ...

Over the course of the next year and a half, the Juno spacecraft will carry out a total of nine flybys of Io. Two of the close encounters will take the probe to within 930 miles of the moon's surface.

Because Io is far from the sun and has a very thin atmosphere, its surface, on average, sits at around minus 200 degrees Fahrenheit, and it is coated in a frosty layer of sulfuric compounds.

Scientists say Earth's Moon went through a period when it was a lot like Io, a moon of Jupiter that's full of volcanic activity. NASA Only 7% of LAist readers currently donate to fund our journalism.

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 ...
