Great Attractor

The Great Attractor is a spot in space on the order of 250 million light-years away, apparently with the mass of many thousand galaxies. It is the location to which Laniakea Supercluster, our local supercluster is apparently drawing its galaxies (a large scale streaming motion toward that point), evident from redshift surveys that indicate galaxy peculiar velocities ranging from -700km/s to +700 km/s. The location is obscured by the zone of avoidance, limiting our knowledge of what is there, but there is a recent report of a supercluster in that direction (Vela Supercluster), that is further than the distance cited for the Great Attractor but would produce some of the noted peculiar velocity distribution.
