Void (astronomy)

In astronomy, voids are the empty spaces between filaments. Filaments and voids are the largest-scale structures in the Universe. There are no or few galaxies in voids. Most voids have a diameter of 11 to 150 Mpc. 
Especially large voids are the empty spaces without many superclusters. 
These voids are sometimes called supervoids.

A 1994 official counting lists a total of 27 supervoids with a distance of up to 740 Mpc.Lindner U, J. Einasto, M. Einasto, W. Freudling, K. Fricke, E. Tago. 1995. The structure of supervoids. I. Void hierarchy in the Northern Local Supervoid., Astron. Astrophys., v.301, p.329
