NASA's Juno revealed mushballs on Jupiter, reshaping our understanding of deep, violent gas giant storm systems.

Imagine a Slushee composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted ...

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 ...

Weather on Jupiter may have some surprising similarities to Earth phenomena, but some things it does defy easy explanation.

Scientists spent four years challenging an out-of-the-box theory that ammonia and water form slushy hailstones on the gaseous planet. Looks like it’s true.

"It was so stunning to not just see the auroras, but the detail and clarity of the signature really shocked me." ...

The weather forecast for Jupiter calls for clouds with a chance of lightning and "mushballs"—a slushy mix of ammonia and ...

A bizarre hailstorm of icy “mushballs” — slushy mixtures of ammonia and water — has been confirmed on Jupiter, where intense ...

Using Webb’s near-infrared spectrograph, astronomers have captured new images of Neptune that finally reveal the planet’s mysterious auroral activity. Faint hints of Neptune’s auroras were first ...

However, imaging and confirming the auroras on Neptune has long evaded astronomers despite successful detections on Jupiter, Saturn, and Uranus. Neptune was the missing piece of the puzzle when it ...

Gas giants like Jupiter and Saturn and ice giants like Neptune and Uranus are a major focus of current space missions and large telescopes, including the James Webb Space Telescope, in part because ...

The planet’s elusive aurorae are much colder than expected, which is how they evaded detection for so long.
