Jupiter System

Scientists have documented atmospheric changes on Io, Jupiter’s volcanically active satellite, as the giant planet casts its shadow over the moon’s surface during daily eclipses.

The Hubble Space Telescope picks up clues from Ganymede's thin atmosphere.

Tides flowing in a subsurface ocean of molten rock, or magma, could explain why Jupiter's moon Io appears to have its volcanoes in the "wrong" place.

Airbus Defence & Space in France has been selected as the prime industrial contractor for ESA’s Juice mission to Jupiter and its icy moons.

bright explosions of Jupiter's aurora likely also get kicked off by the planet-moon interaction, not by solar activity.

NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon.

NASA's Hubble Space Telescope has captured the rare occurrence of three of Jupiter's largest moons racing across the banded face of the gas-giant planet: Europa, Callisto, and Io.

A swarm of tiny probes each with a different sensor could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere.

Getting a handle on what rocky worlds in our solar system would look like from afar will give us a basis for comparison as we seek out distant, habitable exoplanets.
