Examination of a three-dimensional map of galaxies and their velocities shows a surface bounding the motions of galaxies that are inward after removal of the mean cosmic expansion and long-range flows; the galaxies within this surface lie within our home supercluster. This movie accompany the research article "The Laniakea supercluster of galaxies" by R. Brent Tully, Helene Courtois, Yehuda Hoffman et Daniel Pomarède in Nature, vol 513, number 7516, p71 (4 September 2014)
