Jupiter

NASA's mission to Jupiter has revealed new findings about the giant planet and its volcanic moon.

Big storms can strip some parts of Jupiter's atmosphere of ammonia, while leaving buried reservoirs of the gas elsewhere.

A massive solar windstorm in 2017 compressed Jupiter's magnetosphere "like a giant squash ball," a new study reports.

The long-held assumption that Jupiter's iconic swirling clouds are made of frozen ammonia could be upended.

A pair of massive thunderstorms have been spotted swirling in Jupiter's "South Equatorial Belt" and are likely unleashing massive bolts of green lightning. Some experts think the pale clouds could end up altering the rusty band's color — and potentially even making it "disappear."

NASA is developing autonomous software to recognize faults and hazards on worlds like Europa, and prevent or fix them without having to await commands from Earth.

Magnetic vortices twisting down from Jupiter's ionosphere into its deep atmosphere cause giant, ultraviolet-absorbing polar anticyclones, each the size of our Earth.

NASA's Juno spacecraft has sent back stunning photos of Jupiter, including colorful, chaotic storms swirling through the planet’s atmosphere.

Jupiter has no solid ground, like the grass or dirt you tread here on Earth. But how can that be? If Jupiter doesn’t have a surface, what does it have?

Thanks to images from various NASA spacecraft, we can get an up-close look at the Jupiter ocean moon Europa long before the agency's Europa Clipper probe arrives.
