Stargazing Conference |

Stargazing is dependent on clear weather, but lectures and Q&As take place regardless. The event will take place in person, with a talk and Q&A also streamed live on YouTube.

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

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

Galaxies are dynamic, evolving objects made up of stars, gas, and dark matter, and are as diverse as the inhabitants of 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 talk, I will discuss how galactic atmospheres (called the circumgalactic medium) are essential to understanding the evolution of galaxies, 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 emerging from recent research.

About the series
