    With this spectrograph, the most sensitive available in the early 1950s, coupled with the 200-inch telescope, the most powerful in the world, astronomers were able to study the faintest, most distant observable galaxies. Using the spectra it produced, they were able to measure the expansion rate of the Universe with a precision never before possible and show that the universe was older than the Earth and stars.
