What are the most important science discoveries from Kitt Peak?
Galaxy Rotation Curves Study of spiral galaxy rotation curves provided the first indication of dark matter in the universe. Dark matter may dominate over ordinary matter in regulating the dynamics of galaxies and the entire universe. High Redshift Galaxies By using radio emission as a selection criterion, the highest redshift galaxies have been discovered. The systematic study of these galaxies, with redshifts greater than 5 and dating back to very early epochs, has resulted in a new understanding of the rate of galaxy formation. Galaxy Evolution and Environment Observations of galaxy clusters indicate that the environment of a galaxy plays a strong role in its evolution. For example, the local density of galaxies can have an impact upon star formation and stellar populations in those galaxies. Large-scale Structure The discovery of a void in the constellation Boötes lead to an early indication of the large scale structure of the universe. Later research programs established that very
