200 years Fraunhofer's lines
Researcher Joseph von Fraunhofer, born in 1787, brought us closer to the stars. Counted as one of the founders of modern optics, he succeeded in manufacturing telescopes in a quality that had never been seen before. In 1814, he made his most significant discovery, which was then named after him – Fraunhofer lines. These make it possible for us to get a closer look at space and to understand how stars are born.
