List of voids


This is a list of voids. Voids are particularly galaxy-poor volumes of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids.

Voids and supervoids

In the tables, z is the cosmological redshift, c the speed of light, and h the dimensionless Hubble parameter. Mpc stands for megaparsec.
