Astronomy on Tap

"Planetary Defense from Asteroids" and "Gravitational Waves Probing The Big Bang"
Julie Bellerose, DART Navigation Team Chief, Jet Propulsion Laboratory,
Ritoban Basu Thakur, Postdoctoral Researcher, Department of Astronomy, Caltech,

How will we save humanity when an asteroid is on a collision course with the Earth? What can we learn about the moments immediately following the Big Bang from gravitational waves? Join us to learn these answers and more at a night of science on Monday, October 25th at 7:30PM PDT. We'll host two ~15 minute talks, Q&A, and then follow it up with interactive, astronomical pub trivia. Bring a drink!

About the Series

Astronomy on Tap is a nation-wide phenomenon where professional astronomers give informal science talks in local bars with accompanying pub trivia and interactions with the public. Scientists at Caltech organize the Los Angeles Chapter of Astronomy on Tap one Monday a month. Originally held at Der Wolfskopf bar in Old Town Pasadena, we have moved online to virtual events since March 2020.

Each event consists of two ~15-minute informal science talks given by researchers in astronomy, physics, and space science followed by Q&A. The second half of the night is devoted to astronomy-themed pub trivia with lots of interaction with the audience. For more information and recordings of past events, please see the Caltech Astro Outreach website and the Caltech Astro YouTube page.
