Io's volcanic activity explained without magma ocean evidence Tidal heating powers volcanic eruptions on Jupiter's moon ...

NASA's recent flybys of Io, however, reveal that it likely doesn't contain a global magma ocean beneath its surface, as ...

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 ...

If the planet has a liquid ocean underneath, its yellow crust caked in sulfur, it will be more squishable compared to a more ...

Jupiter’s moon Io, is the most volcanic body in the solar system. About 400 volcanoes erupt on its surface, blasting lava and ...

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 ...
