About Huge-LQG

The light we see from it set out 8.89 billion years ago, when the universe was 4.9 billion years old (redshift 1.27).

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

Its distance or nature is debated, and the map shows one published value.

A group of 73 quasars spanning about 4 billion light-years (Clowes et al. 2013). Whether it is a real structure is debated.
