Detailed explanation-1: -On average, the farther away a galaxy is from you, the faster it will appear to recede away from you. This shows up when you look at the colors of the stars present within the galaxy, as well as the emission and absorption lines inherent to the galaxy itself: they’ll appear to be systematically shifted towards the red.
Detailed explanation-2: -Galaxies are moving at a constant speed, the ones further away are so because they move faster. Galaxies move faster away the further they are from each other, because there is more matter between them that expands.
Detailed explanation-3: -As the universe expands, the space between galaxies is expanding. The more distance between us and a galaxy, the more quickly the galaxy will appear to be moving away from us.
