Scientists with NASA's Juno mission to Jupiter have discovered that the volcanoes on Jupiter's moon Io are each likely powered by their own chamber of roiling hot magma rather than an ocean of magma.

Researchers from the Juno mission have finally solved a mystery that has puzzled scientists for over four decades.

Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system.

The north polar region of Jupiter’s volcanic moon Io was captured by NASA’s Juno during the spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. Data from recent flybys is helping ...

NASA's Juno spacecraft captures stunning images of Io's volcanic surface, revealing fresh lava flows and sulfur dioxide gas ...

Io, discovered by Galileo Galilei in 1610, is the most volcanic body in our solar system. NASA's Juno spacecraft continues to ...

Earlier, after Io's volcanic activity was discovered in 1979, scientists thought that the moon has a global magma ocean. But Juno, from its close flybys in December 2023 and February 2024 has helped ...

Io, roughly the size of Earth's Moon, is home to approximately 400 volcanoes that continuously erupt, contributing to its ...

A Cold Moon hangs in the sky while Jupiter still shines bright and the Geminid meteor shower peaks in the sky this week.

NASA's Juno mission revealed that Jupiter's moon, Io, the most volcanic body in our solar system, doesn't possess a global ...

Research conducted by scientists with NASA’s Juno mission has unveiled the mechanisms behind intense volcanic activity on Jupiter’s moon, Io. The findings suggest that the volcanoes on the moon are ...
