The Local Void is a vast, empty region of space, lying adjacent to the Local Group. [ 3 ] [ 4 ] Discovered by Brent Tully and Rick Fisher in 1987, [ 5 ] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments ". [ 4 ]
The Hercules Supercluster separates the Northern Local Void from the Boötes Void. [2] The Perseus–Pisces Supercluster and Pegasus Supercluster form a sheet separating the Northern Local Void and Southern Local Void from the Pegasus Void. [2] Southern Local Supervoid: 96 Mpc 112 Mpc Giant Void: 13 h 01 m +38.7° z=0.116 300-400 Mpc
The KBC Void (or Local Hole) is an immense, comparatively empty region of space, named after astronomers Ryan Keenan, Amy Barger, and Lennox Cowie, who studied it in 2013. [1] The existence of a local underdensity has been the subject of many pieces of literature and research articles.

The Northern Local Supervoid is a region of space devoid of rich clusters of galaxies, known as a void. It is the closest supervoid and is located between the Virgo (Local), Coma and Hercules superclusters. On the sky, it is located between Boötes, Virgo, and Serpens Caput constellations.
Some of the free software mentioned here does not have detailed maps (or maps at all) or the ability to follow streets or type in street names (no geocoding). However, in many cases, it is also that which makes the program free (and sometimes open source [ 1 ] ), avoid the need of an Internet connection, [ 2 ] [ 3 ] [ 4 ] and make it very ...
Void fractions up to 40% were observed in intense breaking events penetrating to depths over 0.5 m confined within the crest trough region. Production of potential energy due to buoyancy of bubbles was nearly instantaneous with the majority of energy dissipating within 0.25 s.
The Southern Local Supervoid is a tremendously large, nearly empty region of space (a void). It lies next to the Local Supercluster, which contains our galaxy the Milky Way. Its center is 96 megaparsecs away and the void is 112 megaparsecs in diameter across its narrowest width. [1] Its volume is very approximately 600 billion times that of the ...
