A very long spectrum of the Sun was chopped in small chunks and then displayed one on top of another. This image was created from a digital atlas observed with the Coude Feed telescope at Kitt Peak National Observatory, near Tucson, Arizona. The images shown here were created to mimic an echelle spectrum, with wavelength increasing from left to right along each strip, and from bottom to top. Each of the 50 slices covers 60 angstroms, for a complete spectrum across the visual range from 4000 to 7000 angstroms. Release date June 1, 2015.
