Milky Way flipped over after colliding with dwarf galaxy 10 billion years ago
Astronomers have discovered that the Milky Way galaxy was flipped upside down about 10 billion years ago after colliding with a smaller dwarf galaxy. This finding, based on data from the Gaia space observatory, provides new insights into the violent history and formation of our galaxy. It reshapes our understanding of galactic evolution and the dynamic events that shaped the Milky Way.
