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

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

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.

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 ...

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

The weather gets a little wild and weird on Jupiter. How wild? Spacecraft instruments have measured strong winds, tracked ...

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

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

and large storms that generate mushballs and lightning. "Every time you look at Jupiter, it's mostly just surface level," Moeckel said. "It's shallow, but a few things—vortices and these big ...
