Galaxies, like cells in the body, are the building blocks of the Universe. Like cells, galaxies themselves are composed of subcomponents: stars, gas, and dust. Some key questions in modern astronomy include: how long after the Big Bang did galaxies start forming, how long ago did galaxies form their stars, and when did they assemble into their current shapes? By studying the stars that make up galaxies we can answer these questions.

Unfortunately, nearly all galaxies are too far away to study their individual stars! So what can we do? In this talk Prof. Scott Trager will describe how stars evolve, how we can understand the light they emit, and how this light combines together to make the light we see from distant galaxies. How can we can dissect this light to learn about the ages and composition of stars in distant galaxies, and what does this tell us about when and how galaxies form, assemble, and change?
