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

New simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field. New Johns Hopkins University simulations offer an ...

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.

Jupiter, the fifth planet in our solar system and by far most massive, is a treasure trove of scientific discovery. Last year a pair of studies found that the planet’s iconic Great Red Spot is 40 ...
