Observing Black Holes

Black holes are fascinating: the densest objects in the universe from which no light can escape. How do you observe something that doesn't emit any light? The first picture of the shadow of a black hole was only taken this year, but astronomers have been studying them for decades through the effect they have on their surroundings. In this lecture we will go over the many methods astronomers use to search for and investigate the properties of black holes of all kinds, from the small ones in our cosmic backyard to the monsters in the centers of galaxies.

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.
