Never-before-seen temperature and ion density measurements reveal that the effect of Jupiter's moons on its aurora are more complicated than scientists thought.

On March 8, 1979, NASA's Voyager 1 spacecraft discovered active volcanoes on Jupiter's moon Io. [‘On This Day in Space’ Video ...

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.

“Our findings suggest that Jupiter’s moons did not form as chemically pristine worlds,” Mousis said. “Instead, they may have accreted, or accumulated, a significant inventory of COMs at birth, ...

Ganymede's auroras splinter into small, bright patches — structures that mirror features seen in Earth's own auroral displays ...

Jupiter’s icy moons may have been seeded with the chemical ingredients for life from the very beginning. An international ...

A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor. We already know a decent amount about how planets form, but moon ...

New research suggests that Jupiter’s icy moons may have formed with complex organic molecules already embedded in their building blocks.

When did Jupiter’s Galilean moons first contain the ingredients for life? This is what complementary studies published in The Planetary Science Journal and Monthly Notices of the Royal Astronomical ...
