In astronomy, voids are the empty spaces between filaments. Both filaments and Voids are one of 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 ("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. Some of supervoids chosen from the list are given below.
|#||Name||Distance (Mpc)||Diameter (Mpc)|
|9||Southern Local Supervoid||135||158|
|24||Northern Local Supervoid||86||146|
