New simulations suggest Jupiter holds far more water than once thought, reshaping ideas about how the largest planet formed.

Jupiter’s swirling storms have concealed its true makeup for centuries, but a new model is finally peeling back the clouds.

Not all of the solar system’s building blocks formed simultaneously. Some of the first solid bodies, or planetesimals, formed in the first million years after the Sun was born. Others, including the ...

Jupiter harbors more oxygen than the sun, a new study finds, giving astronomers a crucial clue about how our solar system's planets formed.

Over four billion years ago, the solar system was a wild and dangerous place. Swirling clouds of dust and gas slowly turned into the planets we know today. One giant, Jupiter, grew quickly and changed ...

Jupiter is the largest planet in our solar system (so large, in fact, that some scientists think it might have even consumed other worlds), a gas giant so massive that it shaped the orbits and ...

Hot Jupiters were once cosmic oddities, but unraveling how they moved so close to their stars has remained a stubborn mystery. Scientists have long debated whether these giants were violently flung ...

"This brings us closer to understanding how not only Jupiter but the entire solar system took shape," said Konstantin Batygin, planetary science professor at Caltech and lead author of the study, in a ...

Thick, swirling clouds cover Jupiter from pole to pole. They hold water like Earth’s clouds, but at far greater density.

An atmospheric study reveals unexpected findings about our largest neighboring planet and the structure of its deep atmosphere.
