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

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 ...

In a new study published in Science Advances, a team led by planetary scientist Chris Moeckel from UC Berkeley offers a ...

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 ...

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

Scientists have discovered that during storms on Jupiter, ice balls containing ammonia and water fall. This unusual ...

Jovian storms can rework the whole chemical makeup of Jupiter's deep atmosphere by picking up ammonia from and dropping it somewhere else. It would appear that a really big storm on Jupiter can ...

Although the impact of Comet Shoemaker-Levy 9 seems like a once-in-a-lifetime event, impacts still occur at Jupiter. You ...

The idea of mushballs was initially put forth in 2020 to explain nonuniformities in the distribution of ammonia gas in Jupiter’s upper atmosphere that were detected both by NASA’s Juno mission and by ...

A cross section of the upper atmosphere, or troposphere, of Jupiter, showing the depth of storms in a north-south swath that crosses the planet's equator, or equatorial zone (EZ). Blue and red ...
