Stargazing Lecture

An Archaeological Road Trip with the Keck Telescope
Evan Kirby, Assistant Professor of Astronomy, Caltech,

The Keck telescopes have gone on an archaeological road trip to the most remote neighborhoods of our galaxy. These neighborhoods are peppered with mini-galaxies-within-a-galaxy that are sparsely populated with just handfuls of stars. Although these galaxies used to harbor supernovae that produced most of the elements in the periodic table, those factories were shuttered long ago. Keck uncovers the history of these ghost towns—and their defunct manufacturing economies—by discovering what the few surviving stars are made of.

About the Series

Stargazing Lectures are free lectures at a public level followed by 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 lasts 90 minutes. Stay only as long as you want.

Stargazing is only possible with clear skies, but the lecture, slideshow, and Q&A takes place regardless of weather.
