Void (astronomy)




Voids typically have a diameter of 11 to 150 Mpc ; particularly large voids, defined by the absence of rich Supercluster s, are sometimes called supervoids.

A 1994 census ("''The structure of the Universe traced by rich clusters of galaxies.''", see References) lists a total of 27 supervoids with a distance of up to 740 Mpc; a selection is given below:
