In this third lecture of three in the Frontiers of Science unit on astronomy, Columbia University professor David Helfand describes methods of detecting other solar systems and planets and their properties in the interest of answering the question: Is our solar system unique, or are there others like it in the Universe? A lecture video and companion PowerPoint presentation are also available on FoSO.

In this second lecture of three in the Frontiers of Science unit on astronomy, Columbia University professor David Helfand explores the life history of a star, a biography encompassing millions of years, and how astrophysicists are able to trace stellar evolution. A lecture video and companion PowerPoint presentation are also available on FoSO.

In this first lecture of three in the Frontiers of Science unit on astronomy, Columbia University professor David Helfand sifts through astrophysics jargon to explain the basic physics behind stars—"our signposts for measuring our place in the Universe and its history"—and how they evolve over cosmic time. A lecture video and companion PowerPoint presentation are also available on FoSO.
