One hundred years ago, astronomers using optical telescopes questioned whether the universe was composed of stars, or of systems of stars called “galaxies.” Since then, this “Great Debate” has shifted to more and more precise questions. The 2020 Exploring Space Lecture Series will feature discussions on some of these questions as we explore the mysteries of the Sun, new information on black holes, and the roles that the Spitzer and Event Horizon telescopes have played in shaping the parameters of this constantly-evolving debate.
