Professor Robert Simcoe is the Director of the MIT Kavli Institute for Astrophysics and Space Research, and one of the world's leading astrophysicists on spectroscopy and the early universe.
In this episode of Astrophysics for All, Rob explains how astronomers use light to study the first stars and galaxies that formed after the Big Bang. He shares why he likes to say that "if a picture is worth a thousand words, then a spectrum is worth a thousand pictures," and reveals how a beam of starlight can tell us about the composition, motion, and history of objects billions of light-years away.
We also discuss what it's like to design and build cutting-edge astronomical instruments, the excitement of detecting photons that have travelled for over 13 billion years, and how telescopes allow us to look back in time and uncover the universe's origin story.
