Great Attractor - English Definition & Meaning

Definition

The Great Attractor is a gravitational anomaly in intergalactic space. Located about 250 million light-years away, it pulls galaxies, including our own Milky Way, towards it. It's in the direction of the constellations Centaurus and Hydra. The exact nature is not fully understood because it's obscured by our galaxy's Zone of Avoidance. Think of it as a cosmic vacuum cleaner sucking everything toward it. It's a super-large concentration of mass, possibly a supercluster of galaxies. This cosmic tug-of-war shapes the large-scale structure of the universe.

Etymology

"Great" implies its significant size and influence. "Attractor" refers to its gravitational pull. The name arose in the 1970s and 1980s as astronomers began to map the movement of galaxies. It reflects our growing understanding of the universe's structure.
