It is not only one of the largest structures known -- it is our home. The
just-identified Laniakea Supercluster of galaxies contains thousands of
galaxies that includes our Milky Way Galaxy, the Local Group of galaxies, and
the entire nearby Virgo Cluster of Galaxies. The colossal supercluster is shown
in the above computer-generated visualization, where green areas are rich with
white-dot galaxies and white lines indicate motion towards the supercluster
center. An outline of Laniakea is given in orange, while the blue dot shows our
location. Outside the orange line, galaxies flow into other galatic
concentrations. The Laniakea Supercluster spans about 500 million light years
and contains about 100,000 times the mass of our Milky Way Galaxy. The
discoverers of Laniakea gave it a name that means "immense heaven" in
Hawaiian.
