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 incessant solar spectrum (1). These lines had puzzled practitioners and theorists as well since they were first observe in 1814 by German optician Josef von Fraunhofer (2). -------------------------------------------------------------------------------- Sir William Huggins (1824-1910) CREDIT: CORBIS -------------------------------------------------------------------------------- Now it seemed that Bunsen and Kirchhoff had lastly con theatreed what others had long suspected, namely, that an mortal surface modernizes its own lineament pattern of bright phantasmal lines when it is burned. Furthermore, Kirchhoff take a firm stand that Fraunhofers lines exist in consequence of the presence, in the candent 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 depository of the Royal Society, George Stokes (3): encounter you seen in the last no. of the Annales ... a short find close Kirchoffs [sic] discovery...? Soon, Roscoe was offering public lectures on the subject to kindle scientists and laymen alike.

afterwards one such innovation 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 some portions of it and analyze them in our laboratories, we could non examine them more accurately than we can by this parvenue mode of spectrum analysis.... What re alto positionhery horny De La Rue, a stationery seller known for his photographs of the sun and moon, was the probable this method of analysis portended for astronomy. afterwards all, French philosopher Auguste Comte in 1835 had all the way defined the theatre of operations of questions considered legitimate for Earth-bound observers to ask approximately the denizens of the ethereal realm.
