Stargazing Lecture

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: https://youtu.be/xmxW7z7IjfY

7:00–7:30 p.m. - Public Lecture
7:30–9:00 p.m. - Panel Q&A and Guided Stargazing

Galaxies are dynamic, evolving objects consisting of stars, gas, and dark matter, and are as diverse as the people on this planet. In order to understand why galaxies look the way they do and why some die (stop forming new stars) while others thrive, it is important to understand the environment in which they live. In this lecture, I will discuss how galactic atmospheres (referred to as the circumgalactic medium) are key to understanding galaxy evolution, and perhaps, our own existence in the Milky Way. I will highlight recent observations, taken with the Hubble Space Telescope, that challenge existing theoretical models and discuss possible solutions from recent research.

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.
