The force propelling the Milky Way through space has been a mystery to scientists for decades — but now a new 3D map has shed light on the mystery.

Previously it was thought a dense region of the universe was pulling us toward it, through the sheer might of its gravity — with a gravitational force equivalent to a million billion suns.

This initial suspect was called the Great Attractor, a region of clusters of galaxies 150 million light years from the Milky Way.
