Most of the elements that we interact with on a regular basis were originally synthesized inside stars or during their explosions. The heaviest of elements, such as gold, platinum, and uranium are thought to be primarily produced in extremely dense, neutron-rich, energetic explosions such as the mergers of neutron stars. In this talk, I will share a few different possible origin stories for how these rare, heavy elements came to populate the Earth and our Universe using clues from galactic archaeology, geochemistry, and rapid astronomical observations.

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 and are Free and open to all. No reservations are needed. Lectures are 30 minutes; stargazing and panel Q&A last 60 minutes. Stay only as long as you want.

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