NASA's EUNICE Will Provide Spectra Images (image) NASA/Goddard Space Flight Center Caption Unlike a conventional image, NASA's Extreme Ultraviolet Normal Incidence Spectrograph will provide what's known as "spectra" such as above, which show lines to highlight which wavelengths of light are brighter than others. That information, in turn, corresponds to which elements are present in the sun's atmosphere and at what temperature.
