Milky Way Altered Orientation After Collision

An astronomical study has revealed that the Milky Way galaxy flipped more than 90 degrees after colliding with a dwarf galaxy called "Gaia Soysog" approximately 10 billion years ago, long before the formation of the solar system by billions of years. The collision occurred when the dwarf galaxy impacted the Milky Way, causing it to tear apart and absorb its stars, gradually reorientating its axis to its current position. Researchers used computer simulations showing that this flip could explain the slow movement of stars in the galaxy's halo, a process that took hundreds of millions of years, and contributed to the formation of the galaxy's central bulge and its current shape, with expectations of future mergers with other galaxies.
