Description
The Boötes Void ( boh- OH-teez) (colloquially referred to as the Great Nothing ) is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing very few galaxies, hence its name. With a radius of 62 megaparsecs (nearly 330 million across light-years), it is one of the largest voids in the universe, and is referred to as a supervoid.
It was discovered in 1981 by Robert Kirshner as part of a survey of galactic redshifts. Its centre is located 700 million light-years from Earth, and at approximately right ascension 14h 50m and declination 46°.
The Hercules Supercluster forms part of the near edge of the void.
