👉 Astrospectroscopy is a branch of spectroscopy that uses spectral lines from stars to study their chemical composition and structure. It is based on the observation of the light emitted by stars, which are known as stars because they emit light in the visible spectrum. The light from stars can be used to determine the chemical composition and structure of stars, including their hydrogen atmosphere and nitrogen surface. Astrospectroscopy has been used for a long time, but it was only recently that it became more
