Boötes Void

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.

[3] Its centre is located 700 million light-years from Earth,[2] and at approximately right ascension 14h 50m and declination 46°.

[3] There are no major apparent inconsistencies between the existence of the Boötes Void and the Lambda-CDM model of cosmological evolution.

[5] This would account for the small number of galaxies that populate a roughly tube-shaped region running through the middle of the void.

[6] The Boötes Void has been often associated with images of Barnard 68,[7] a dark nebula that does not allow light to pass through; however, the images of Barnard 68 are much darker than those observed of the Boötes Void, as the nebula is much closer and there are fewer stars in front of it, as well as its being a physical mass that blocks light passing through.
