The earliest stars were very different from subsequent stellar generations. It was the later generations that produced almost all of the chemical elements, among them, the elements that make life possible. Dr. Simcoe explains how the universe became transparent, how the first stars possibly formed and how subsequent generations evolved. We learn how today’s sophisticated optical telescopes penetrate billions of light years to the early universe and how astronomers distinguish “early” from “recent” stars and galaxies. Bonus: we learn how to analyze the chemistry of the stars with spectroscopy!
Dr. Simcoe specializes in observational astrophysics, with particular emphasis on the chemistry of galaxies and intergalactic matter in the early universe. He and his colleagues have developed a number of optical tools that serve the most advanced astronomical investigations of the universe.
