A chapter by Fr. Christopher Corbally, S.J., an astronomer with the Vatican Observatory, for the book The Heavens Proclaim: Astronomy and the Vatican. Fr. Corbally writes “the really interesting details contained within a [spectrum] are revealed when light from a star is focused onto a narrow slit, which from there passes through a prism, and then gets focused again onto your eye or a camera.” Topics include ‘A History of Stellar Spectra’; ‘Spectra and Brightness’; ‘Classifying Stars’; ‘Getting to Know Our Neighbors’; and ‘The Simple Picture Gives Way to Surprises’.
