dc.description.abstractFirth in a series of transcribed lectures on Astronomy by Francis J. Heyden, S.J., Director of the Georgetown Observatory. "The Astronomer's Yardstick" explores how astronomers measure the enormous distances between planets and to remote stars and galaxies. Scientists have developed instruments so accurate that they are now approaching the limits of the visible universe and must come up with new methods of measuring the areas of outer space beyond the visible universe.en
