Great Attractor

The Great Attractor is a gravity anomaly in intergalactic space within the range of the Hydra-Centaurus Supercluster that reveals the existence of a localized concentration of mass equivalent to tens of thousands of galaxies, each of which represents the mass of the Milky Way ; this mass is observable by its effect on the motion of galaxies and their associated clusters over a region hundreds of millions of light-years across.

These galaxies are all redshifted, in accordance with the Hubble Flow , indicating that they are receding relative to us and to each other, but the variations in their redshift are sufficient to reveal the existence of the anomaly. The variations in their redshifts are known as peculiar velocities, and cover a range from about +700 km/s to −700 km/s, depending on the angular deviation from the direction to the Great Attractor.

Location
The first indications of a deviation from uniform expansion of the universe were reported in 1973 and again in 1978. The location of the Great Attractor was finally determined in 1986, and is situated at a distance of somewhere between 150 and 250 Mly (million light years) (47–79Mpc) (the latter being the most recent estimate) from the Milky Way, in the direction of the constellations Triangulum Australe (The Southern Triangle ) and Norma (The Carpenter’s Square ).While objects in that direction lie in the Zone of Avoidance (the part of the night sky obscured by the Milky Way galaxy) and are thus difficult to study with visible wavelengths, X-ray observations have revealed that the region of space is dominated by the Norma cluster  a massive cluster of galaxies containing a preponderance of large, old galaxies, many of which are colliding with their neighbours, and/or radiating large amounts of radio waves.

Science Corps and Asrographic Society
In 5080 (OTT) the Assembly approved the construction of the Super Array -Isah ELT- (expansion of the Z Point Station ) aiming to deepen the fundamental knowlege of the Universe by building the largest and most advanced telescope. The Super Array project aims to map the visible Universe using visual, radio and X Ray telesopes (as well as detectors for Tachyons, Psionic chatter, Hyper Pulse ,Gravitons,Neutrinos and other emissions )

First part is the visual inspection of the Great Attractor and surrounding space.

Part of the Gate Mapping Project is the Attractor Expedition (Convoy left M-0 in 5066 (ott) to jump from Ancient Gate to Ancient Gate into the direction of the Great Attractor to determine how far the Gate Network reaches.

The Astrographic Society proposed to use the Great Attractor as focal point of a new navigation and coordinate system.
