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

Jupiter and Saturn may be similar in size and made of the same gases, but the weather at their poles tells a different story.

Spectacular clouds swirl across the surface of Jupiter. These clouds contain water, just like Earth's, but are much denser on the gas giant—so thick that no spacecraft has been able to measure exactly ...

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

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

Jupiter and Saturn host strikingly different polar storms, despite being similar giant planets, and scientists have long wondered why. New simulations suggest the answer may lie deep below the clouds.

The abundance of oxygen inside Jupiter is a major, unsolved problem. For decades, researchers have argued about this value, ...

Katharina Lodders, Ph.D., Washington University in St. Louis research associate professor in Earth and Planetary Sciences in Arts & Sciences, studying data from the Galileo probe of Jupiter, proposes ...

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 ...

A newly discovered planet has the diameter of Jupiter but eight times its mass, giving it twice the density of Earth despite being composed mostly of gas. Not only have these characteristics of this ...
