• Resumen

  • The Milky Way has had a sheltered life. A search for the signs of a violent galactic upbringing has come up empty, and the finding is helping astronomers understand the galaxy's history and could also aid the search for dark matter. Galaxies are shape-shifters and far from being a single set of stars in an eternal spiral, the Milky Way has devoured countless smaller galaxies over its 13 billion year lifetime, and its shape has been in constant flux to accommodate the immigrants. It is riddled with alien stars, threshed from foreign galaxies.
