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.”” [Robert Bunsen](https://sms4smile.com/quotes/author/robert-bunsen/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Bunsen describes how Kirchhoff’s discovery of dark lines in the solar spectrum enables chemical analysis of celestial bodies. **In simple terms:** Kirchhoff’s work lets us identify elements in stars by their light. Key Takeaway Use spectral lines to determine composition.
