The cataclysmic collision took place about 10bn years ago when the Milky Way was struck head-on by an incoming dwarf galaxy known – for purely astronomical reasons – as the Gaia Sausage. The Milky Way tore the interloper to shreds and absorbed its stars, but the chaos unleashed in the event probably flipped the entire disc of the Milky Way by more than 90 degrees into the position seen today, researchers said.
