A massive upheaval in the Saturnian system could have also led to the moon Hyperion.

Of the solar system’s planets, Saturn piques the human imagination with its signature rings and impressive moon count of 274. But compelling new research reignites theories of an ancient collision ...

If Titan formed from a merger, the researchers found, its eccentric orbit could destabilize smaller moons closer to Saturn, ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini's 13-year mission expanded our understanding of ...

Extreme solar activity or even a software glitch could put us just days away from a satellite collision in low-Earth orbit.

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

This hypothesis has the advantage of explaining why the rings have a lot of ice and little rock, in contrast to models where a moon strayed inside Saturn’s Roche limit and was pulled apart.

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow ...

The collision may also be linked to the formation of the planet's iconic rings.

Armageddon might not have a reputation as a scientifically accurate film. But scientists now say the Hollywood blockbuster got one thing right - we really could nuke an asteroid if it were heading for ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...
