Computer simulation of the wake created by the Large Magellanic Cloud, distorting the Milky Way's galactic halo. NASA/JPL-Caltech/NSF/R. Hurt/N. Garavito-Camargo & G. Besla This visualization, taken from the video animation, shows the central disk of our Milky Way galaxy (small blue circle in center) and a smaller nearby galaxy called the Large Magellanic Cloud (red dot and line). A new, all-sky star map charts the location of stars in the Milky Way’s outer reaches, known as the galactic halo, about 200,000 light years to 325,000 light years from the Milky Way’s center.
