A large unseen force is pushing the Milky Way galaxy across the universe, according to new research published Monday in the journal Nature Astronomy.
Researchers have always known the Milky Way is moving across the expanding universe at a relative speed of about 1.24 million miles per hour, according to the New York Post.
Scientists initially thought our galaxy was simply being pulled through space, but now new research suggests it's also being pushed.
For a long time, scientists have known the Milky Way galaxy is attracted to the Shapley Supercluster, which is essentially a large concentration of galaxies located 750 million light-years away, CNN reports.
Still, astronomers weren't convinced this pull was the only factor influencing the Milky Way's movement.
Researchers used data from NASA's Hubble Space Telescope to create a 3-D map of the universe in order to determine where the "push" was coming from.
By doing so, Brent Tully, one of the authors of the study, and his colleagues identified the Dipole Repeller.
The Dipole Repeller has the opposite effect of the Shapley Supercluster.
Scientists said the Dipole Repeller is low in density so it pushes the Milky Way galaxy away from it, whereas, the Milky Way is pulled and attracted to the Shapley Supercluster because of its high density.
Researchers told CNN they are hopeful this will increase our understanding of how the universe works.
