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

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

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

Juno is scheduled for an upcoming flyby of Jupiter on May 7, during which it is set to carry out a close approach of the ...

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

Consider the astronomical and physical possibility of a gas giant's stellar transformation.

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.
