Scientists are uncovering evidence that ancient cosmic collisions fundamentally shaped our solar system's architecture. From galactic mergers that restructured the Milky Way to asteroid impacts that melted the moon's surface and forged Saturn's rings, new research reveals how violence in space created the worlds we observe today.
·A galactic collision 11 billion years ago may have reset the Milky Way's disk structure
·A 3.5 billion-year-old lunar impact melted the moon's surface, documented in rare meteorite analysis
·Saturn's rings and moon Titan formed through ancient collisions between moons
·Mars's lumpy interior was shaped by violent ancient collisions, confirmed by NASA's InSight lander data
·A lone Neptunian moon survived as the intact remnant of an ancient collision that destroyed others
