	Great Attractor - Wikipedia, the free encyclopedia
		The Great Attractor is a gravitational anomaly in intergalactic space at the centre of the local supercluster which reveals the existence of a localised concentration of mass equivalent to tens of thousands of galaxies, observable by its effect on the motion of galaxies over a region hundreds of millions of light years across.
		Attempts to further study the Great Attractor and other phenomena are hampered due to line of sight obstruction by its location in the zone of avoidance (the part of the night sky obscured by the Milky Way galaxy).
		The Great Attractor is an element of Stephen Baxter's Xeelee Sequence of novels (eg.

	Great Attractor
		The intersection of the Centaurus Wall and the Great Attractor includes the Norma Cluster or Supercluster -- ACO 3627, Abell 3627, or A3627 (Woudt et al, 2000, 1999a, and 1999b).
		The Great Attractor's core region appears to be dominated by the Norma Supercluster, a highly obscured, nearby, and massive group of galaxies close to the plane of the Milky Way (Woudt et al, 1999a and 1999b; Kraan-Korteweg et al, 1996; and Patrick Alan Woudt, 1998 PhD thesis).
		Indeed, spectroscopic observations support the idea that the Norma Supercluster is the dominant component of a "Great Wall"-type of structure and is comparable in size, richness and mass similar to Coma in the northern part of the Great Wall (Woudt et al, 2000; and 1997).

	Great Attractor
		Some astronomers believe that the Great Attractor may be centered on the rich cluster known as Abell 3627; others propose that, while there may be a cluster of galaxies in the area of the Great Attractor, the large-scale movement of so many superclusters is probably due to the gravitational pull of all clusters combined.
		One argument against the existence of the Great Attractor is that no one has detected signs of infalling galaxies behind the Attractor.
		On the other hand, it is possible that this infall may be counteracted by the mass of the more distant Shapley Concentration whose galaxies may be tugging the Great Attractor galaxies the other way.

	X-rays Reveal What Makes the Milky Way Move (Site not responding. Last check: 2007-10-21)
		The Great Attractor is what is known as a supercluster, that is, a group of clusters of galaxies, and was estimated to contain matter equal to more than over 10 million billion times the mass of the sun.
		Until now, efforts to find the Great Attractor were hampered by its location in the "zone of avoidance," an area behind the plane of the Milky Way where gas and dust within our galaxy block much of the visible light from objects outside it.
		The finding of a less massive Great Attractor and the large distance to the Shapley supercluster implies that extremely massive overdensities are rare in the Universe, which brings the suggested density of the Universe in line with the density established by independent means.

		The strange attractor in this case is a fractal of Hausdorff dimension between 2 and 3.
		The Great Attractor is a gravitational anomaly in intergalactic space, at the centre of the local supercluster, which is drawing in galaxies over a region hundreds of millions of light years across.

	The Great Attractor (Site not responding. Last check: 2007-10-21)
		It is as if a great river of galaxies (including our own) is flowing with a swift current of 600 km/s toward Centaurus.
		Detailed investigation of that region of the sky (see adjacent image of the galaxy cluster Abell 3627) finds 10 times too little visible matter to account for this flow, again implying a dominant gravitational role for unseen or dark matter.
		Thus, the Great Attractor is certainly there (because we see its gravitational influence), but the major portion of the mass that must be there cannot be seen in our telescopes.

		AFTER nearly a decade of searching, astronomers have at last found the dense core of the Great Attractor, the huge cluster of galaxies that is dragging everything in our neighbourhood towards the southern constellation Norma.
		Renée Kraan-Korteweg of the University of Paris-Meudon and her colleagues have found that a galaxy cluster called Abell 3627 is much bigger than anyone thought, and appears to be the centre of the Great Attractor.
		The hunt for the Great Attractor began in 1987, when astronomers found that nearby galaxies are moving at an average of between 500 and 600 kilometres per second towards a spot in the southern sky.

	Re: If Omega = 1
		Make sure to avoid the common misconception that the Great Attractor is some huge mass that is "sucking in" all of the matter around it.
		Galaxies are still expanding away from the Great Attractor, due to the overall expansion of the universe, but its gravity is making them expand away more slowly than average.
		There is a galaxy cluster at about the position where astronomers think the Great Attractor is located, but whether it is the Great Attractor, or just happens to be at the same spot isn't known.

		This motion can only be accounted for by gravitational attraction, even though the mass that we can observe is not nearly great enough to exert that kind of pull.
		The only thing that could explain the movement of Andromeda is the gravitational pull of a lot of unseen mass--perhaps the equivalent of 10 Milky Way-size galaxies--lying between the two galaxies.
