About Dipole Repeller

The light we see from it set out 0.697 billion years ago, when the universe was 13.1 billion years old (redshift 0.05).

The map lists it as a cosmic void 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.

An underdense region that effectively pushes the Local Group away (Hoffman et al. 2017). Position approximate.

From Wikipedia

The dipole repeller is a center of effective repulsion in the large-scale flow of galaxies in the neighborhood of the Milky Way, first detected in 2017. It is thought to represent a large supervoid, the Dipole Repeller Void.
