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

The appearance of one of Saturn's smallest moons lends it the nickname "Death Star," but astronomers say new evidence suggests the world is, in fact, home to an ingredient vital for life: water. And ...

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 ...

What processes are responsible for shaping Jupiter and Saturn’s polar weather? This is what a recent study published in the ...

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 atmospheric carbon dioxide was thought to be the result of the oxidation of oxygen molecules in the exosphere. As a consequence of this discovery, Rhea became the first Saturnian moon, and only ...

Saturn's moon Mimas has a giant impact crater, named Hershel, that stretches across a third of its surface and makes it resemble the "Death Star" from Star Wars. NASA / JPL / Space Science Institute ...
