Astronomers identify 10bn-year-old galactic collision that reoriented the Milky Way

Researchers from Durham University have identified evidence that a head-on collision with the 'Gaia Sausage' dwarf galaxy 10 billion years ago fundamentally altered the Milky Way's orientation. This finding provides a new structural history for the galaxy, though the precise mechanics of the impact's long-term gravitational influence remain a subject of ongoing astrophysical modeling.
