The Boötes Void (colloquially referred to as the Great Nothing) 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 (nearly 200 million light-years), it is one of the largest known voids in the visible universe, and is often referred to as a supervoid.
