Answer :
Galaxies move away from us in all directions because the universe is expanding regularly.
Hubble's law, also known as the Hubble–Lemaitre law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. When one looks over smaller distances, though, galaxies can mutually attract each other due to gravity, thus are in fact moving toward each other. Our Milky Way and the nearby Andromeda Galaxy are two examples of such a pair of galaxies that are moving toward each other due to gravity. The galaxies outside of our own are moving away from us, and the ones that are farthest away are moving the fastest. This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you.
