Joseph von Fraunhofer lived from 1787-1826. He became the director of a scientific institute in Germany. He made some of the best telescope lenses, which he was trained to do. He identified the dark absorption lines that are in the solar spectrum. These lines show scientists which chemical elements are in light.

The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
Studying Fraunhofer lines helps identify the chemical composition of stars. These lines represent specific wavelengths of light that are absorbed by elements in a star's atmosphere. By analyzing the pattern of these lines, astronomers can determine which elements are present in the star.
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.
If Society was created in 1999.
Mythopoeic Society was created in 1967.
