Saturn now has at least 145 moons and probably possessed many before it developed rings. Scientists have argued that the immense gravity of the sun may have gradually destabilized some of the ...

This is far, far later than the when Saturn itself first formed—around 4.2 billion years ago—and means the planet's iconic feature probably only appeared after the dinosaurs went extinct ...

Nestled inside a planetary ring 110 light-years from Earth, a planet spotted by the James Webb telescope is the lightest ...

While Saturn’s rings may disappear in less than 100 million years because gravity is pulling them into the planet, apparently they haven’t always surrounded the planet, either. The finding was ...

Researchers now appreciate that gas planets are more complex than first thought. New findings have implications for our ...

TOI-4860b is a fairly nearby planet in another star system located just 260 light-years away. It’s also quite strange. It’s a ...

It’s not the first time a formation has appeared, seemingly out of nowhere, on a world beyond Earth. Usually, it’s Mars: this year alone the Mars Reconnaissance Observer spotted a brand-new ...

Without its rings, Saturn looks really boring. Super blah. Erase those bangles—as blogger Jason Kottke did (above) from a NASA photo—and the planet is the blandest sphere in our solar system.

TOI-6894 b, the largest exoplanet relative to its host star yet seen, doesn’t fit the most widely accepted formation model ...

Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The discovery defies current understanding of how planets form.

Saturn’s rings will be edge-on twice in 2025, in March and November. From 2019 to 2023, ... irregular moons can tell us more about the formation of its beautiful rings.

With its striking rings and tilted axis, Saturn is the showiest planet in the solar system. Now, scientists say they have a new theory as to how Saturn got its signature look.
