How One Simple Discovery Changed Astrophysics Forever

Описание: This video examines the origins and development of spectroscopy in astrophysics, beginning with Newton’s prism experiments. It highlights key contributions by Fraunhofer, Kirchhoff, and Bunsen in transforming light analysis into a powerful astronomical tool. Spectroscopy now enables the study of composition, motion, and physical conditions of celestial objects.
