Nearby superclusters and voids

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)
1   188 124
5   182 130
9 Southern Local Supervoid 135 158
18   168 144
19   168 152
20 Bootes Void 304 110
21   201 163
24 Northern Local Supervoid 86 146
