How do scientists understand the chemical composition of our universe, study it's age and determine the reactive processes constantly taking place at temperatures reaching many million Kelvin? The answer is Spectroscopy. This educational program is aimed at upper-level High School students studying astronomy, chemistry and physics. Spectroscopoy is the measurement of the response of matter as it interacts with light. Its many uses extend beyond space to science, to weather monitoring, medical diagnostics such as MRI, household conveniences like the microwave oven and countless other facets of everyday life. This documentary examines the critical role spectroscopy plays in studying the nature, composition, history and future of the Universe.
