Executive summary: Spectroheliograph

In 1893, astronomer Henri Alexandre Deslandres invented the spectroheliograph, an instrument used for taking photographs (called spectroheliograms) of the Sun at a single wavelength of light. He calculated the rotation rates of Jupiter, Uranus, and Saturn and its rings, and studied solar activity and the effects of military bombing on rainfall. His work formed the basis for empirical laws that describe banding patterns in molecular spectra.
