Walls and filaments of Super clusters, 1 billion light years

1On yet a larger scale we see that Super Clusters are forming vast walls and sheets with empty regions - called voids - in between.

This diagram shows many of these Super Clusters including the Virgo super cluster, quite insignificant in the centre.

In this region with a radius of 1 billion light years there are about 100 Super Clusters, some of which are named in the diagram.

1 billion light years correspond in our scale model to a distance of 9.5 billion km, which is about twice the radius of Neptune's orbit around the Sun.
