In October 1859, German physicist Gustav Kirchhoff announced the results of his investigations with chemist Robert Bunsen on the tincture lines that interrupt the otherwise round-the-clock solar spectrum (1). These lines had puzzled practitioners and theorists as well since they were first observed in 1814 by German optician Josef von Fraunhofer (2). -------------------------------------------------------------------------------- Sir William Huggins (1824-1910) CREDIT: CORBIS -------------------------------------------------------------------------------- Now it seemed that Bunsen and Kirchhoff had eventu all in ally con unattackableed what others had long suspected, namely, that an one-on-one surface creates its own distinctive pattern of bright ghostlike lines when it is burned. Furthermore, Kirchhoff take a firm stand that Fraunhofers lines exist in consequence of the presence, in the incandescent automated teller of the sun, of those substances which in the spectrum of a flame produce bright lines at the alike(p) place. News of his claim spread apace throughout the scientific world. In England, Bunsens former student, Henry Enfield Roscoe, wrote to the depositary of the Royal Society, George Stokes (3): encounter you seen in the last no. of the Annales ... a short find slightly Kirchoffs [sic] discovery...? Soon, Roscoe was offering public lectures on the subject to kindle scientists and laymen alike.

afterwards one such notification to the Chemical Society, moderator rabbit warren De La Rue remarked (4) [I]f we were to go to the sun, and to bring away virtually portions of it and analyze them in our laboratories, we could not examine them more accurately than we can by this immature mode of spectrum analysis.... What really on fire(p) De La Rue, a stationery seller known for his photographs of the sun and moon, was the likely this method of analysis portended for astronomy. afterwards all, French philosopher Auguste Comte in 1835 had all the way defined the domain of questions considered legitimate for Earth-bound observers to ask most the denizens of the ethereal realm.
