Boötes Void

The Boötes Void is a roughly spherical region of space in the vicinity of the constellation Boötes. It contains just 60 galaxies, which is significantly fewer than the approximately 2,000 galaxies expected for an area of comparable size. With a radius of 62 megaparsecs, it is one of the largest known voids in the visible universe, and is often referred to as a "supervoid".
