Kate Follette (Section 01)


What is the shape of the universe? How do stars die? What happens when galaxies collide? This course will provide an introduction to the nature and evolution of stars, our Milky Way galaxy, other galaxies, and the origin, size, shape and fate of the universe itself. We will explore how the fields of extragalactic astronomy and cosmology emerged and continue to evolve, and will touch on many of the big unanswered questions in these fields. Our investigations of galactic and extragalactic phenomena will focus on understanding proportionalities, relative sizes, and visual representations of data, as well as evaluating the reasonableness of quantitative answers rather than on lengthy calculations.

Limited to 60 students. Fall semester. Professor Follette.
