With a radius of 62 megaparsecs (nearly 330 million light-years across), it is one of the largest voids in the visible universe, and is referred to as a supervoid. [2] It was discovered in 1981 by Robert Kirshner as part of a survey of galactic redshifts. [3]

The simultaneous existence of the largest-known voids and galaxy clusters requires about 70% dark energy in the universe today, consistent with the latest data from the cosmic microwave background. [5] Voids act as bubbles in the universe that are sensitive to background cosmological changes.

Aug 1, 2022 · The Boötes void, often referred to as the Great Nothing or the Great Void, is an actual area of space with fewer galaxies than you'd expect. At 250 to 330 million light-years across, it is one of...

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.

Boötes is one of the largest, earning it the title of ‘supervoid’. It’s thought that Boötes is the product of smaller voids merging together. The cause of these voids is thought to lie in the …

Feb 26, 2024 · As the map of the universe unfolded, a vast, nearly empty region emerged, aptly named the Boötes Void. Stretching over 700 million light-years from Earth, this void became a cosmic enigma, capturing the imagination of scientists and space enthusiasts alike.

Aug 24, 2007 · Radio astronomers have found the biggest hole ever seen in the universe. The void, which is nearly a billion light years across, is empty of both normal matter and dark matter. The finding...

With an estimated diameter of nearly 330 million light-years—constituting approximately 0.27% of the observable Universe's diameter—or a volume of almost 236,000 Mpc3, the Boötes Void is recognized as a 'supervoid,' making it one of the Universe's largest known voids.

May 21, 2024 · The Boötes void is the largest void in the known universe. It is a region 250 million light-years across, located in the direction of the constellation Boötes, which only contains a few dozen galaxies strewn in a rough tube shape through the middle.

The center of the Boötes void, also known as the Great Void, is about 215 Mpc away from the Milky Way. It is a near spherical region of space, some 75 to 100 Mpc across. It contains a much lower density of galaxies than expected, and to date, only about 60 galaxies have been found in the void, although there are probably more dwarf galaxies ...
