A computer-generated visualization of the Laniakea Supercluster, our galactic home. Green areas show galaxy density, white lines depict galactic motion toward the supercluster's center (shown in blue). The supercluster's outline is orange; it's 500 million light-years across and contains 100,000 times the mass of our Milky Way.
