Stargazing Lecture

Planetquake: what vibrations can tell us about the interiors of gas giant planets
Janosz Dewberry, Postdoctoral Fellow, Department of Astronomy, Caltech,

This is back to occurring in-person, so if the weather allows, we will host our telescope-aided stargazing. Event will be hybrid, so we'll stream the lecture and the panel Q&A over YouTube livestream. In-person audience members will be required to prove full vaccination status at the door and wear a mask while in indoor spaces as per Caltech policy.

Join the YouTube Livestream here:

8:00–8:30 p.m. - Public Lecture
8:30–10:00 p.m. - Panel Q&A and Guided Stargazing

Conditions deep inside Jupiter and Saturn are hard to measure directly. Luckily, seismic vibrations similar to earthquakes provide a window into the internal structures of both planets. I will talk about what we can learn from vibrations in Saturn that disturb the planet's rings, and how waves in both Jupiter and Saturn may affect the outward travel of their satellite moons.

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.
