About the Shapley Supercluster

The light we see from it set out 0.656 billion years ago, when the universe was 13.1 billion years old (redshift 0.047).

The map lists it as a supercluster and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

The most massive concentration of galaxies within about a billion light-years.

From Wikipedia

The Shapley Supercluster or Shapley Concentration is one of the largest concentrations of galaxies in the observable universe that forms a bound, gravitationally interacting unit, thereby pulling itself together instead of expanding with the universe.
