  • 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:

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

Humans can only see a narrow range of wavelengths of light, but the electromagnetic spectrum of light covers a much broader range. Radio telescopes can "see" many objects in space that our eyes cannot, including flashes given off by highly magnetic stars, energetic jets erupting from black holes, and radiation emitted from supernovae. But how do these radio telescopes work and how can we build one? Over the last several years, I have been working on a new radio telescope called SPRITE in the desert north of Los Angeles. I will discuss how this telescope works, how we built it, and how we can use it to make new astronomical discoveries.

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 60 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.
