Where is the Boötes Void?
Boötes Void
Size: 330 million light years Object type: Cosmic void
1 The void’s centre lies 700 million light years away from Earth. It was discovered in 1981, and the Hercules Supercluster forms one edge.
Coma
Size: 20 million light years Object type: Supercluster 2 In Coma Berenices lies this supercluster containing over 3,000 galaxies. It’s the central component of the Coma Great Wall and is also part of the Coma Filament.
Corona Borealis
Size: 150 million light years Object type: Cosmic void
3 This void lies next to the Microscopium Void and is surrounded by the Ophiuchus, Hercules and Centaurus superclusters. It is next to the Coma Great Wall.
Hydra-Centaurus
Size: 250 million light years Object type: Supercluster 4 A twin-lobed supercluster that’s 150 million light years away at its closest. It is the nearest such structure to our home supercluster of Virgo.
Virgo
Size: 110 million light years Object type: Supercluster
5 The supercluster in which we reside contains the Local Group of galaxies, of which we are a part. Virgo is 110 million light years in size with a mass of 1.48 x 1015 solar masses.
A3627 (the Norma cluster)
Size: Unknown
Object type: Supercluster
6 220 million light years away, Norma is largely obscured behind a region of the Milky Way called the Zone of Avoidance.
Microscopium Void
Size: Unknown
Object type: Cosmic void 7 A roughly rectangular-shaped region of space near the
Corona Borealis Void and the Capricornus Void, it lies above the Norma Supercluster.
Pavo-Indus
Size: Unknown
Object type: Supercluster 8 Located 196 million light years away, Pavo-Indus is a lobe of the much larger Laniakea Supercluster, which was discovered in 2014.
Capricornus
Size: 230 million light years Object type: Cosmic void 9 A 230 million light yearwide void in the Capricornus constellation, making it one of the biggest ever known, but is smaller than Boötes.
Sculptor
Size: Unknown
Object type: Cosmic void
10 Many objects in the universe are named after Sculptor. This void is separated from the supposed Eridanus Void by a sheet of galaxies and lies next to the Sculptor Wall.
Canis Major
Size: Unknown
Object type: Cosmic void
16 This lies next to the PerseusPisces Supercluster on one side and close to the Hydra lobe of the Hydra-Centaurus Supercluster on the other.
Perseus-Pisces
Size: Unknown
Object type: Supercluster 15 A supercluster lying 250 million light years away, it also forms part of the 1 billion light year-long Perseus-Pisces Filament of galaxies.
Columba
Size: 150 million light years Object type: Cosmic void
14 Similar in size to the Corona Borealis Void, Columba lies between the Fornax and Canis Major voids. The associated constellation lies between Caelum, Canis Major and Puppis.
Fornax
Size: Unknown
Object type: Cosmic void
13 This roughly spherical void lies beyond the Sculptor Wall and next to the Columba Void, with only a thin stream of galaxies separating them.
Phoenix
Size: Unknown
Object type: Supercluster
12 Part of the Sculptor Wall, this lies next to the Sculptor Void in the Phoenix constellation. The Phoenix Supercluster is 400 million light years from Earth.
Sculptor Wall
Size: 326 million light years Object type: Supercluster
11 Also called the Sculptor Supercluster and the Southern Great Wall, it measures 326 by 228 by 33 million light years and is one of a handful of cosmic ‘wall’ structures.
