From its beginnings in the early 19th century, spectroscopy — the analysis of starlight by wavelength — has unlocked a treasure-trove of astronomical information. Most of what we know about a star's chemical composition, temperature, axial spin, magnetic field, and motion through space is deduced by studying its spectrum.
