Jupiter is famous for its striking, stripey appearance, looking like an orange and white marble covered in streaky, complex patterns. But as a gas giant, Jupiter doesn't have a solid surface made of ...

Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real ...

Jupiter is a massive, terrifying planet. Despite being studied for centuries and even visited by nine space probes in the ...

The Juno spacecraft orbiting Jupiter just revealed mechanisms driving mammoth storms in the Jovian atmosphere. Storms on Jupiter form ammonia-rich hail — called mushballs — in the atmosphere of the ...

Using the NASA/ESA/CSA James Webb Space Telescope, scientists observed the region above Jupiter's iconic Great Red Spot to discover a variety of previously unseen features. The region, previously ...

Jupiter has some of the most conspicuous atmospheric features in our solar system. The planet's Great Red Spot, large enough to envelop Earth, is nearly as well known as some of the various rivers and ...

NASA’s James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter’s atmosphere. The high-speed jet stream is more than 3,000 miles (4,800 km) wide, in contrast to just a few ...

The Great Red Spot is a massive storm on Jupiter that swirls in a counterclockwise motion. It’s a turbulent and chaotic place, to be sure. But scientists thought the upper atmosphere directly above ...

Io, Jupiter’s innermost moon, is the most volcanically active body in the solar system, and its molten eruptions belch out enough sulfur dioxide gas to envelop this little world in a thin atmosphere.

New Earth-based telescope observations show that auroras at Jupiter’s poles are heating the planet’s atmosphere to a greater depth than previously thought — and that it is a rapid response to the ...

Imagine a Slushee TM composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted slushballs, dubbed “mushballs,” raining down like hailstones during a ...
