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

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

Blue and red represent, respectively, higher- and lower-than-normal abundances of ammonia gas. By tracking the ammonia, two ...

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 ...

For instance, the Hubble Space Telescope entered safe mode relatively recently as scientists worked on remedying some ...

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 ...

Normally, Jupiter's powerful polar auroras inject significant heat into the gas giant's upper atmosphere near the poles. These spectacular lights resemble those seen on Earth, where they're ...

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 ...
