[11] [12] The National Radio Quiet Zone Administrator at the Green Bank Observatory manages the enforcement policies. Zones 1 and Zone 2 are located within the property of the Green Bank Observatory. The entire property is designated Zone 1 except small portions (such as housing, visitor, and laboratory areas) that are designated Zone 2.
A radio quiet zone is an area where radio transmissions are restricted in order to protect a radio telescope [1] or a communications station [2] from radio frequency interference. The Radio Regulations of the International Telecommunication Union (ITU) define interference as being detrimental to radio astronomy if it increases measurement ...
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.
A dead zone is an area of water that cannot sustain aquatic life because the oxygen levels are low or depleted. The scientific term for a dead zone is called hypoxia, which in Latin means "too ...
Red circles show the location and size of many dead zones (in 2008). Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century.

It is believed that these disks consist of a turbulent envelope of plasma, also called the active zone, that encases an extensive region of quiescent gas called the dead zone. [14] The dead zone located at the mid-plane can slow down the flow of matter through the disk which prohibits achieving a steady state.
