Milky Way’s Ancient Galactic Collision | Australia News

Our Milky Way isn’t just sitting still—it’s a cosmic collision survivor, shaped by massive mergers over billions of years. While we knew about the giant “Gaia-Sausage-Enceladus” merger 10 billion years ago, new research reveals an even older, colossal crash 12 billion years back—introducing the mysterious “Low-energy-Kraken-Heracles.” Scientists uncovered this by studying ancient star clusters like galactic fossils, finding distinct stellar layers that map out our galaxy’s violent past. This discovery deepens our understanding of how the Milky Way grew to its current size and structure, turning us into cosmic archaeologists piecing together galactic history. And the story? Far from over—our galaxy’s still merging with neighbors like Sagittarius, and may one day collide with Andromeda. The universe keeps rewriting its own saga, and we’re just beginning to read the chapters. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
