List of voids

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

In the tables, z is the cosmological redshift, c the speed of light, and h the dimensionless Hubble parameter, which has a value of approximately 0.7 (the Hubble constant H₀ = h × 100 km s⁻¹ Mpc⁻¹). Mpc stands for megaparsec.

The co-ordinates (right ascension and declination) and distance given refer to the approximate center of the region.
