Titan may be the battered survivor of a colossal moon merger that reshaped Saturn’s rings and rewrote the planet’s history.

Saturn’s largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds of millions of years ago—an event so violent it reshaped Saturn’s entire moon system and may have indirectly sparked the formation of its iconic rings. Clues come from Titan’s unusual orbit, its surprisingly smooth surface, and the strange behavior of the tumbling moon Hyperion.

New research suggests that Saturn’s brilliant rings and its largest moon, Titan, may share a violent past shaped by c...

An international team of astronomers has discovered a titanic structure in the early Universe, just two billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance. It has a mass estimated at a million billion Suns.

Largest galaxy proto-supercluster found. An international team of astronomers has discovered a titanic structure in the early Universe, just 2 billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance.

The team that made the discovery was led by Olga Cucciati of Istituto Nazionale di Astrofisica (INAF) Bologna, It...
