A Galaxy's red-shift can be used to determine how fast it is travelling away from you. The opposite is "blue-shift" which is what happens when the Galaxy is travelling towards you.The first astronomers, such as Edwin Hubble, to analyse the light coming from distant galaxies discovered that almost all of them were red-shifted, indicating that they were almost all heading away from us. This was the first indication that the universe was expanding.
