Course on the Great Attractor

Shapley supercluster, discovered in 1930. Harlow Shapley, is the most massive supercluster of galaxies of the 220 known superclusters in the observable universe. It contains a mass of about 10, 000 times greater than the mass of the Milky Way and 4 times greater than the mass observed in the "Great Attractor".

The same study was carried out, which allowed the calculation of the contribution to the velocity of the local group from the Great Attractor is 44%, the rest is associated with the global trend, where much of the local universe, including himself "The Great Attractor" is moving towards an even stronger center attraction, near the Shapley supercluster.

Recently, in August 2014. astronomers have constructed a three-dimensional visualization of the Laniakea supercluster, which includes Virgin and supercluster containing our own "Milky Way". So, the whole area can be represented as Laniakea valley surrounded by mountains from which to the lowest point of the valley flow down rivers and streams.

"Low Point" is a new "Great Attractor" and is the heart of Laniakea.

[Thuh Uhbuhv] map (which looks down onto the supergalactic plane) shows all of the major clusters of galaxies between us and the Shapley supercluster. Our Galaxy is located at the lower-left, and between us and the Shapley supercluster lies the Centaurus supercluster. At a distance of 650 million light years, the Shapley supercluster is a dense collection of approximately 20 major clusters of galaxies contained within a region that is not much larger than the Virgo supercluster (which only contains one major cluster).

In the middle of the Shapley supercluster are several massive clusters. The Abell catalogue contains only five clusters of galaxies with a richness class above 2 within one billion light years from us. Three of these clusters (A3558, A3559 and A3560) are in the Shapley supercluster. The fourth cluster (A3128) is in the Horologium supercluster, and the fifth cluster (A3301) is on the edge of the Horologium supercluster. These clusters are some of the richest clusters of galaxies known and some of them contain more galaxies than the very rich Coma cluster.

The Shapley Supercluster is a famous supercluster.

This is a list of the major clusters of galaxies in the Shapley Supercluster. There are 25 clusters of galaxies in this list (which does not include the four clusters in the Centaurus supercluster). Seven of these clusters have a richness class of 2 or higher, which means (roughly) that there are seven clusters here which are as rich as the Perseus or Coma clusters…

Column 1: The name/number of the cluster or group.
Column 2: The Right Ascension for epoch 2000.
Column 3: The Declination for epoch 2000.
Column 4: The redshift of the cluster.
Column 5: The distance in millions of light years assuming H=70km/s/Mpc.
Column 6: The 'richness' class of the cluster (for Abell clusters only).
Column 7: Additional names and notes…

Below is a list of five other major groups of galaxies in the Shapley Supercluster. The SC1327-312 and SC1329-313 groups are particularly famous because they lie near the centre of the supercluster between the A3558 and A3562 clusters.
