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.

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.

Apr 15, 2024 · It is the largest cosmic void we know of, spanning 2 billion light years. Our galaxy happens to be near its centre, but the trouble with this hole isn’t that it presents a proximate danger – more...

The Local Void is a vast, empty region of space, lying adjacent to the Local Group. [3] [4] Discovered by Brent Tully and Rick Fisher in 1987, [5] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments". [4]

Jun 14, 2017 · Earth and its parent galaxy are living in a cosmic desert — a region of space largely devoid of other galaxies, stars and planets, according to a new study. The findings confirm the results of a...

Feb 23, 2025 · Cosmic voids that stretch across millions even billions of light years of spacetime make up most of the volume of the observable universe. In fact, our own Milky Way Galaxy is thought to be...

Dec 7, 2023 · In our new paper, we present one possible explanation: that we live in a giant void in space (an area with below average density). We show that this could inflate local measurements through...

Nov 18, 2024 · Recent studies suggest that the Milky Way might sit within an enormous cosmic underdensity known as the The universe is full of mysteries, and one of the most intriguing is the so-called Hubble tension—an inconsistency in the rate at which our universe is expanding.

May 28, 2024 · In the vast expanses of the universe, cosmic voids present one of the most enigmatic phenomena in astrophysics. These immense, nearly empty spaces, punctuate the cosmic landscape, contrasting starkly with the densely packed galaxies and galactic clusters.

Oct 20, 2024 · The Mystery: An Empty Cosmic Void Beyond Our Reach. This supergiant, or supervoid, is the space in that is almost empty, containing galaxies, stars, and matter some many orders of magnitude fewer than a typical region of the universe.
