Galaxies change over time, but those changes take millions or billions of years – far longer than the human lifetime. To understand how galaxies evolve, astronomers therefore need to study large numbers of galaxies at various stages. NASA’s Nancy Grace Roman Space Telescope will revolutionize galaxy studies since it can survey the sky up to thousands of times faster than can be done with Hubble at similar image sharpness (resolution). It will reveal how galaxies assembled and transformed over the history of the universe.
