Jupiter

NASA's Juno probe continues to give us more insight into Jupiter and the giant planet's moons, including Io, the most volcanically active object in the solar system.

Jupiter's moon Io is the solar system's most volcanic body thanks to a gravitational tug of war that rages below its surface. But now scientists know the violent moon has always been this way.

The Hubble Space Telescope's latest look at Jupiter finds writhing storms and a shrinking Great Red Spot.

A time-changing jet in Jupiter's atmosphere may finally shed light onto the gas giant’s mysterious dynamo.

NASA's Juno probe made a close approach of Jupiter's moon Europa, finding possible proof of present day surface activity.

A Very Large Telescope instrument designed to study exoplanets has turned its focus to our own cosmic neighborhood to measure Jupiter's wind speeds.

NASA's Juno spacecraft will come closer to Jupiter's moon Io on Dec. 30 than any spacecraft has in 20 years, getting a good look at the solar system's most volcanic body.

The spacecraft recently burned 10 percent of its total fuel in a single 43-minute maneuver as preparation for the double gravity assist.

Jupiter's moon Io, the most volcanically active world in the solar system, may possess a global ocean of magma underneath its surface, as well as mysteriously warm poles, a new study finds.

NASA's Juno spacecraft has found that Jupiter's winds whip around the planet's turbulent atmosphere cylindrically.
