  • Public Event

Stargazing is dependent on clear weather, but lecture and Q&A happen regardless. Event will occur in-person, with lecture and Q&A additionally live-streamed on YouTube.

For remote viewers, the event will be live-streamed here:

8:00–8:30 p.m. - Public Lecture
8:30–9:45 p.m. - Panel Q&A and Guided Stargazing

The first billion years after the Big Bang represent the final frontier in assembling a complete picture of cosmic history. During this period early galaxies formed and the universe first became bathed in light. How and when did all this occur? Recent progress with the James Webb Space Telescope suggests we may soon witness this dramatic period when the universe emerged from darkness. I will describe the astonishing progress in this quest up to and beyond the launch of JWST. The motivation is fundamental: the origin of starlight began the process of chemical evolution which ultimately led to our own existence in this remarkable universe.

About the Series

Stargazing Lectures are free lectures at a public level followed by a Q&A panel and guided stargazing with telescopes (weather permitting). All events are held at the Cahill Center for Astronomy and Astrophysics at Caltech. No reservations are needed. Lectures are 30 minutes; stargazing and panel Q&A last 90 minutes. Stay only as long as you want.

Stargazing is only possible with clear skies, but the lecture and panel Q&A takes place regardless of weather.
