 There's one more thing about the galaxies in our local superclusters. They all have an unusual peculiar motion. Normally, galaxies are expected to have a motion consistent with the Hubble flow, that is, given Hubble's law and the distance to a galaxy, its velocity is set. But in our local area, within one billion light years, there is an additional flow superimposed on the Hubble flow. It appears that our galaxy, and a large number of the galaxy clusters in our area, are flowing towards what is called the Great Attractor. Our velocity is estimated to be around 700 km per second towards this point. That's 435 miles per second. Recent observations indicate that the point is the place all the galaxies in the Elania Chia supercluster are moving. The mass at this theoretical location is estimated to be thousands of times more than the mass of the entire Milky Way. Here's a panoramic view of the entire sky as seen in near infrared. It shows the distribution of galaxies beyond the Milky Way. The galaxies are color coded by red shifts, obtained from various sky surveys. Blueish-purple are the nearest sources within 140 million light years. Green are at moderate distances out to 600 million light years. And red are the most distant sources out to a billion light years. Initially, it looked like the Great Attractor was located close to the Norma cluster. But Norma is so close to our galactic plane or area of avoidance that we cannot see into it very well. More recently, updates of motion vectors indicate that the flow is not so much to the Norma cluster, but to the much more massive Shapley Galaxy cluster. As you can imagine, understanding this peculiar flow is an area of active research.
