The Gaia-Enceladus dwarf galaxy crashed into our Milky Way 11.5 billion years ago and combined the mass of 50 billion suns to our galaxy. Now the new insights of this collision come from a single bright star visible in Southern Hemisphere skies. There’s a new episode in the tale of an ancient collision between our Milky Way and a now-mostly-defunct dwarf galaxy called Gaia-Enceladus. A disagreement situation with this galaxy was first introduced in 2018, based extensively on data from the European Space Agency’s great Gaia mission.
