Jupiter System

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.

Over two weeks in August 2013, Io exploded as a potential window into our past and many planets’ presents.

Three massive volcanic eruptions occurred on Jupiter’s moon Io, a satellite the size of Earth’s moon, within a two-week period last August.

Processes that shaped the ridges and troughs on the surface of Jupiter's icy moon Ganymede are likely similar to tectonic processes seen on Earth.

A new NASA-funded study has shown that Jupiter's moon Ganymede might have layers of ice and oceans sandwiched together beneath its surface.

Is Jupiter a friendly planet, Earth's enemy, or perhaps both?

Using images from NASA’s Voyager Mission (1979) and the orbital Galileo Mission (1995), researchers have created the first global geological map of Jupiter’s largest moon, Ganymede.

A new study explains why Jupiter's Giant Red Spot exists today, even though fluid dynamics suggest that it should have faded centuries ago.
