    [synopsis] => Starting with the spectrum of sunlight, notice that thin, dark lines are present at certain wavelengths. These lines reveal the composition and temperature of the Sun's outer atmosphere, and similar lines characterize other stars. More diffuse phenomena such as nebulae produce bright emission lines against a dark spectrum. Probe the quantum and thermodynamic events implied by these clues.
