The presentation explores the intimate relationship between astronomy and the Periodic Table, highlighting how our understanding of the Universe arises from the analysis of distant starlight—light emitted by atoms as they change energy states. It begins with an overview of the history of the Universe, tracing the origin of atoms and the forces that bind them together. The talk then explains how the electron shell structure responsible for light emission also organizes the elements within the Periodic Table. The role of spectroscopy is examined, revealing information about the composition of matter, its relative motion, and even the expansion of space itself. All of these insights stem from interpreting the atomic “fingerprints” found in light that atoms emit and absorb. The presentation concludes with examples from the speaker’s work on the Sloan Digital Sky Survey.Larry Bartoszek
