Online and In-Person Event
Chuck Steidel (PhD '90), Lee A. DuBridge Professor of Astronomy, Division of Physics, Mathematics and Astronomy, Department of Astronomy,
  • Public Event

Since it began its scientific mission in July 2022, the James Webb Space Telescope (JWST) has provided the first detailed glimpses of the most distant reaches of the observable universe, when the first galaxies were emerging more than 13 billion years ago. History suggests that opening new observational windows leads to entirely unanticipated discoveries, and JWST has already begun to fulfill that promise. In this lecture, Steidel will explore what enables the unprecedented power of JWST for studying galaxy formation in its infancy and what we can expect to learn from JWST images and spectra over the next several years.

This lecture will be presented in a hybrid format, allowing for both virtual viewers and in-person attendees. No advance registration is required for either format but you may sign up for reminders about this event.

About the Series

The 2022–2023 season marks the centennial of The Earnest C. Watson Lecture Series, which has brought Caltech's most innovative scientific research to the public since the Friday Evening Demonstrations premiered in October of 1922. The series is named for Earnest C. Watson, a professor of physics at Caltech from 1919 until 1959. The Watson Lectures are geared toward a general audience, as part of the Institute's ongoing commitment to benefiting the local community through education and outreach.

Many past Watson Lectures are available on YouTube.
