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

For generations, Jupiter has been shorthand for a straightforward idea: the biggest planet in the Solar System, a gas giant ...

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

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

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.

Towering clouds ripple across Jupiter's surface in dramatic patterns. Like Earth's clouds, they contain water, but on Jupiter they are far denser and ...

Jupiter and Saturn's different polar storms reveal clues about planet interiors: Saturn has harder bottom than Jupiter.

For three months, the Hubble Space Telescope stared at the famous blemish on Jupiter. What the veteran spacecraft found surprised NASA scientists. Jupiter’s Great Red Spot (GRS) is “jiggling like a ...

Over the years, passing spacecraft have observed mystifying weather patterns at the poles of Jupiter and Saturn. The two planets host very different types of polar vortices, which are huge atmospheric ...

Over the years, passing spacecraft have observed mystifying weather patterns at the poles of Jupiter and Saturn. The two ...

The very bright "star" you see in the eastern sky after sunset is actually the planet Jupiter. It is just coming off ...
