    A map of the Boötes Void. The Boötes Void (/ b oʊ ˈ oʊ t iː z / boh-OH-teez) (colloquially referred to as the Great Nothing) [1] is an approximately spherical region of space found in the vicinity of the constellation Boötes, containing only 60 galaxies instead of the 2,000 that should be expected from an area this large, hence its name.

    Requiring 19 different facilities on the Earth and in space, this image reveals the enormous scales spanned by the black hole and its forward-pointing jet. It shows the image of the larger-scale jet taken by ALMA (upper left), on the same scale as the visible image by the Hubble Space Telescope (center) and the X-ray image by Chandra (upper right).

    Size comparison of the event horizons of the black holes of TON 618 and Phoenix A.The orbit of Neptune (white oval) is included for comparison. As a quasar, TON 618 is believed to be the active galactic nucleus at the center of a galaxy, the engine of which is a supermassive black hole feeding on intensely hot gas and matter in an accretion disc.

    It possesses a diffuse core which is the largest known core of any galaxy to date, [5] and contains a supermassive black hole, one of the largest discovered. [5] IC 1101 is located at 354.0 megaparsecs (1.15 billion light-years) from Earth. It was discovered on 19 June 1790, by the German-British astronomer William Herschel. [6]
