“At the moment I am occupied by an investigation with Kirchhoff which does not allow us to sleep. Kirchhoff has made a totally unexpected discovery, inasmuch as he has found out the cause for the dark lines in the solar spectrum and can produce these lines artificially intensified both in the solar spectrum and in the continuous spectrum of a flame, their position being identical with that of Fraunhofer’s lines. Hence the path is opened for the determination of the chemical composition of the Sun and the fixed stars.” ScienceStarsSunDiscoveryAstronomyChemistryInvestigationCauseFraunhoferGustav KirchhoffJoseph Von FraunhoferKirchhoff Author:Robert Bunsen
“Look here, I have succeeded at last in fetching some gold from the sun. {After his banker questioned the value of investigating gold in the Fraunhofer lines of the sun and Kirchhoff handing him over a medal he was awarded for his investigations.}” ScienceSunGoldChemistryExperimentSpectroscopyFraunhoferJoseph Von Fraunhofer Author:Gustav Kirchhoff
