Great Attractor

The Great Attractor is a broad region of enhanced gravitational influence in the nearby Universe, associated with galaxy motions toward the Norma Cluster and embedded in the larger Laniakea Supercluster. Its study is complicated by foreground stars and dust in the Milky Way, which obscure much of the region at visible wavelengths.

Meaning and location

The Great Attractor is not a single compact body. The name describes a concentration of mass and associated gravitational-flow region inferred from the peculiar motions of nearby galaxies. It lies in the direction of the Norma Cluster (Abell 3627), a massive cluster on the border of the constellations Norma and Triangulum Australe. NASA describes the cluster as about 220 million light-years away.

Galaxy motions and Laniakea

The gravitational influence of large-scale structure alters galaxies' motions relative to the smooth expansion of the Universe. In 2014, a team using galaxy-velocity data mapped the Laniakea Supercluster, a vast region whose internal galaxy motions converge toward a broad gravitational basin. The Great Attractor is a focal region within this larger flow pattern, rather than a solitary cosmic object pulling everything toward one point.

Why it is difficult to observe

The Great Attractor lies behind the plane of the Milky Way. Stars in our Galaxy outshine background objects, while interstellar dust absorbs and scatters visible light. Infrared and radio observations can reveal galaxies hidden in this Zone of Avoidance, though the densest central regions remain challenging to map.
