IN PERSON: The knowledge of our vast universe beyond the few thousand stars we can see with the naked eye depends on telescopes. This course explores the transformative role of telescopes in expanding our knowledge of the cosmos. We’ll begin with the history of optical telescopes and the key discoveries they enabled. Moving beyond visible light, we will survey how modern telescopes allow us to see across the electromagnetic spectrum — from radio to gamma rays — revealing the universe’s most extreme phenomena. We will also discuss exotic telescopes that detect gravitational waves and neutrinos, providing insights on topics beyond traditional light-based astronomy. Emphasis is on the scientific knowledge gained rather than technical aspects of building or using telescopes, providing students with a broad view of the cosmos. | Lecture + Q&A.

Don Ellison received his Ph.D. from The Catholic University of America in Washington, D.C., in 1982. He then pursued postdoctoral positions in France, at the University of Maryland and at NASA/Goddard Space Flight Center before moving to NC State University in 1987. Besides teaching physics and astrophysics at NC State, his research has concentrated on the theory of cosmic ray origin, particle acceleration in high-energy astrophysics and the evolution of supernova remnants.
