Large hailstones made of ammonia may explain why the gas is missing from large pockets of Jupiter's atmosphere.

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

When you think of oceans you probably think of water, but the most massive reservoir of liquid in the solar system is made ...

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

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

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

A burst of solar wind triggered a planet-wide heatwave in Jupiter’s upper atmosphere, say astronomers at the University in ...

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

The atmosphere on Jupiter is radically different from that on Earth. It's primarily made of hydrogen and helium gas with trace amounts of gaseous molecules, like ammonia and water, which are ...

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 ...
