Weird reporting like this is "new" GRB ring out of Swift and Sloan SDSS data.

Sloan Great Wall, which is around 1.5 billion light-years in length

South Pole Wall, which stretches 1.4 billion light-years across.

Hercules-Corona Borealis Great Wall, which is about 10 billion light-years wide

2015 https://en.m.wikipedia.org/wiki/Giant_GRB_Ring

It is approximately 9.1 billion light years from Earth and about 5.6 billion light years across.

Evidence suggests that this feature is the projection of a shell on to the plane of the sky. Voids and string-like formations are common outcomes of large-scale structure. However, these structures have maximum sizes of 150 Mpc, which are an order of magnitude smaller than the observed GRB ring diameter. Evidence in support of the shell interpretation requires that temporal information of the transient GRBs be included in the analysis. This ring-shaped feature is large enough to contradict the CP. The physical mechanism responsible for causing it is unknown.

A very approachable and knowledgeable pair of science communicators have an excellent recent podcast episode explaining these structures to the best of our current knowledge.

Seems that sky surveys at those extreme distances reveal that quasars are grouped together in ways consistent with our concept of structure, the way we understand and define it.

If we could see this (alleged) structure with the naked eye, it would span the length of 15 moons end-to-end in the sky... and it is at least 9 billion lightyears away. Remarkable, absolutely incredible that we can detect these things, these patterns.
