Void (astronomy) Guide, Meaning , Facts, Information and Description
In astronomy, voids are the empty spaces between filaments, one of the largest-scale structures in the Universe that contain none or hardly any galaxies. Voids typically have a diameter of 11 to 150 Mpc; particularly large voids, defined by the absence of rich superclusters, 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:
| # | 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 |
