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 ...

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

Jupiter is known for its stormy weather, featuring cyclones, anticyclones, large storms, and ammonia-rich plumes that engulf the planet. The planet’s atmosphere is primarily made of hydrogen and ...

Jovian storms can rework the whole chemical makeup of Jupiter's deep atmosphere by picking up ammonia from and dropping it ...

There is a key difference between Jupiter's lightning and Earth's, however. On our planet, lightning storms are clustered in the tropical regions around the equator. That's because warm air allows ...

Scientists have finally proved that Jupiter gets slammed by bizarre "mushballs", solving a long-standing space mystery ...

A pair of planetary scientists at the University of California, working with a colleague from the California Institute of ...

Jupiter experiences a unique weather phenomenon where mushballs, ice-encrusted slushballs of ammonia and water, rain down like hailstones.

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 ...
