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

The Japanese asteroid-sampling spacecraft Hayabusa2 has been forced into protective "safe mode" while journeying through deep space.

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 ...

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 ...
