Astrophysicists Help Chart Dark Matter s Invisible Ocean A wake of stars, created by a small galaxy set to collide with the Milky Way, is the highlight of a new map of the Milky Way s outer reaches. The observations confirm predictions made by a group of UArizona astronomers whose computer simulations test theories explaining the mysterious nature of dark matter. By Daniel Stolte, University Communications April 21, 2021 Images of the Milky Way and the Large Magellanic Cloud (LMC) are overlaid on a map of the surrounding galactic halo. The smaller structure is a wake created by the LMC’s motion through this region. The larger light-blue feature corresponds to a high density of stars observed in the northern hemisphere of our galaxy.
