Boötes Void

The Boötes Void (/boʊˈoʊtiːz/ 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 only 60 galaxies instead of the 2000 that should be expected from an area this large, hence its name. 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.

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 14^h 50^m and declination 46°.

The Hercules Supercluster forms part of the near edge of the void.
