His visible and infrared spectroscopic studies of planets led to the determination of rotation periods and the identification of molecules in planetary atmospheres. He discovered reflection nebulae and proved the existence of interstellar dust and gas. Using exposure times as long as 80 hours, he was the first to discover and measure the enormous radial velocities of spiral nebulae; these data served as the basis of modern observational cosmology. His major contribution was determining that the spectra of the vast majority of external galaxies had red shifts. This crucial discovery laid the foundation for Hubble's law and the theory of the expansion of the universe.

Carrington for the independent and nearly simultaneous discoveries of two solar features of great importance: by 1860,  both astronomers had accumulated sunspot observations demonstrating the differential rotation of the Sun's surface, as inferred from the apparent east-west motion of sunspots; and the gradual drift toward the equator through the descending period of the sunspot cycle (now often called Spörer's Law).
