Voids are particularly galaxy-poor regions of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids . In the tables, z is the cosmological redshift , c the speed of light , and h the dimensionless Hubble parameter , which has a value of approximately 0.7 (the Hubble constant H 0 = h × ...
A map of the Boötes Void. The Boötes Void (/ b oʊ ˈ oʊ t iː z / boh-OH-teez) (colloquially referred to as the Great Nothing) [1] is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing only 60 galaxies instead of the 2,000 that should be expected from an area this large, hence its name.
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.
Cosmic voids (also known as dark space) are vast spaces between filaments (the largest-scale structures in the universe), which contain very few or no galaxies. In spite of their size, most galaxies are not located in voids. This is because most galaxies are gravitationally bound together, creating huge cosmic structures known as galaxy filaments.
The group discovered the unfathomable supervoid that is 1.8 billion light-years across, according to Sky News.A section of space of that size would typically house 10,000 galleries.

In astronomy, voids are the empty spaces between filaments (some of the largest-scale structures in the Universe) that contain hardly any, or no, galaxies. Pages in category "Voids (astronomy)" The following 13 pages are in this category, out of 13 total.
There is something missing in our understanding of the Universe to explain its expansion, known as dark energy, that began after the Big Bang, according to a new study using James Webb Space ...
