Observations from the James Webb Space Telescope show how Jupiter reacts to its moons through auroral footprints, plasma interactions, and rapid electron flows detected in infrared measurements.

Using the Webb telescope, scientists discovered an unexpectedly cold, dense region within Io’s auroral footprint in Jupiter’s northern lights.

Jupiter's moon Io stands alone among the solar system's moons. It has more than 400 active volcanoes, and its surface is home to more than 100 massive volcanic mountains, some of which are taller than ...

NASA has recorded the most powerful volcanic eruption outside of Earth on Io, one of Jupiter’s moons. On December 27, 2022, Juno, NASA’s spacecraft, witnessed numerous active volcanoes erupting ...

A new analysis of data from NASA’s Galileo spacecraft reveals a subsurface “ocean” of magma–either molten or partially molten–beneath the surface of Jupiter’s volcanic moon Io. The finding, from a ...

Io transits Jupiter, showing us how quickly our view can change — now that we are a few days past opposition, the moon and its shadow won’t quite overlap, but instead Io’s shadow will now trail it ...
