The Great Attractor is a gravitational anomaly in intergalactic space that is pulling the Milky Way and hundreds of thousands of other galaxies towards it at high speed. Here are the key points about the Great Attractor:
- It is located approximately 150-250 million light years from the Milky Way in the direction of the constellations Triangulum Australe and Norma[1]. However, it is difficult to observe directly because it lies in the Zone of Avoidance, a region obscured by the Milky Way's galactic plane[1].
- The Great Attractor's gravitational pull is causing the Local Group of galaxies, including the Milky Way, to move towards it at about 600 km/s (1.3 million mph)[1][5]. Approximately 400 elliptical galaxies have been observed moving in its direction[1][5].
- The mass concentration at the Great Attractor is estimated to be equivalent to tens of thousands of galaxies[1]. X-ray observations have revealed that the Norma Cluster, a massive cluster of galaxies, lies at its center[1].
- However, the Norma Cluster alone does not fully explain the gravitational effects observed[2]. On an even larger scale, the Great Attractor itself is being pulled towards the Shapley Supercluster, an enormous concentration of over 8000 galaxies with a total mass of more than 10 million billion suns[1][2].
- Despite its pull, the expansion of the universe will eventually cause the Local Group and other galaxies to disperse away from the Great Attractor in the distant future[3][5]. So while it is a significant gravitational influence, it will not consume the Milky Way or nearby galaxies.
In summary, the Great Attractor is a region of gravitational anomaly that is pulling our galaxy and many others towards it, but its effects are part of the complex cosmic flows in our expanding universe. It remains an intriguing subject of ongoing astronomical research.

Beyond the Observable Universe
What we perceive to be the edge of our universe is not the actual edge of the universe, with most scientists in agreement that more space lies hidden beyond what we're able to see. Wade out into the darkness of the unobservable universe.
