About the Big Ring
The light we see from it set out 7.03 billion years ago, when the universe was 6.76 billion years old (redshift 0.8).
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.
Key numbers
| Distance (comoving, today) | 9.35 billion light-years (2,868 Mpc) |
|---|---|
| Redshift z | 0.8 |
| Light travel time | 7.03 billion years |
| Universe's age when this light left | 6.76 billion years |
| Distance method | redshift (Planck 2018 cosmology) |

From Wikipedia
The Big Ring is a ring-shaped large-scale structure formed by galaxies and galaxy clusters near the constellation Boötes with a diameter of 1.3 billion light years, located 9.2 billion light years away. It was discovered in 2024 by Alexia Lopez, a PhD student at the University of Central Lancashire.
