Something Invisible Is Pulling Our Entire Galaxy Toward It at 2 Million km/h
Answers: “what is the great attractor?”
Right now, you’re moving. Not just Earth around the Sun, or the Sun around the galaxy — the entire Milky Way is being pulled through space at roughly 2 million kilometers per hour, along with thousands of other galaxies, all streaming in the same direction.
Toward what?
Astronomers call it the Great Attractor — a name that’s half description, half confession of ignorance. It’s a region of space about 150–250 million light-years away whose gravity is herding every galaxy in our cosmic neighborhood, and for decades we couldn’t even look at it properly.
Here’s the maddening part: the Great Attractor sits almost exactly behind the plane of our own galaxy. The Milky Way’s dense band of stars, gas, and dust blocks our view like a hand held in front of a telescope. Astronomers literally call this strip of sky the Zone of Avoidance.
What we’ve pieced together, peering through the murk with X-ray and infrared telescopes:
- A massive concentration of galaxies — the Norma Cluster — lies in the right direction, but it doesn’t seem heavy enough to explain the pull
- Behind it looms something bigger: the Shapley Supercluster, one of the most massive structures in the known universe, which may be the true anchor
- Our whole local group of galaxies appears to be one small current in a vast river of matter flowing across hundreds of millions of light-years
In 2014, astronomers mapped these flows and found we belong to a colossal structure they named Laniakea — Hawaiian for “immense heaven” — 100,000 galaxies drifting together, with the Great Attractor region at its gravitational heart.
You will never feel it. But you’ve never once been standing still.
