In the late 1920 ’ s, Hubble also discovered that these galaxies are receding from us and that the greater the distance they are away, the faster they are receding.
Divdesmito gadu beigās Habls atklāja arī to, ka galaktikas no mums attālinās, turklāt, jo lielāks ir attālums līdz kādai galaktikai, jo straujāk tā attālinās.
