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

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

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.
