| contents | Continuing professional development for teachers in the physical sciences is crucial to maintaining high-quality instruction, especially when addressing modern physics. Nevertheless, the teaching of these topics often relies on theoretical models that may seem abstract and removed from practical applications. In this context, research in astrophysics provides many valuable insights into the nature of light and its fundamental properties, such as continuous and discrete spectra, blackbody radiation, and atomic orbitals. This paper, aimed at both high school and university-level physics teachers, examines the peculiarities of the emission and absorption spectra of various types of astronomical objects and demonstrates how spectroscopy is applied in astrophysics research. From this perspective, the study conceptually illustrates how astrophysicists, by measuring light spectra, determine the composition, physical properties, origin, and evolution of celestial bodies and, by extension, of the universe as a whole. By understanding not only the theory but also the direct applications of astronomical spectroscopy, teachers will be better prepared to guide their students, thereby showcasing the true value of modern physics in the real world. |
