Caption: A study of 544 star-forming galaxies observed by the Keck and Hubble telescopes shows that disk galaxies like our own Milky Way unexpectedly reached their current state long after much of the universe's star formation had ceased. Over the past eight billion years, the galaxies lose chaotic motions and spin faster as they develop into settled disk galaxies.
