The Department of Astronomy and Astrophysics and the UC Observatories present the eighth Mandel Lecture: The Hubble Deep Field 30 Years Later

Under the direction of then-director of the Space Telescope Science Institute, Bob Williams, the Hubble Space Telescope was pointed at a seemingly empty patch of sky for 10 days. The result of that image, filled with thousands of unknown galaxies, forever changed the way we look at the universe.

Join us as Bob Williams, a scientist who witnessed it all, discusses the observations of distant galaxies made by the Hubble Space Telescope and how these discoveries shed light on the history and evolution of the universe's large-scale structure.

Bob Williams is currently Director Emeritus at Space Telescope Science Institute (STScI) in Baltimore, and the Donald Osterbrock Visiting Professor at the University of California, Santa Cruz.
