UPDATE: DUE TO A NEW STORM SYSTEM ARRIVING MONDAY NIGHT, WE ARE POSTPONING MONDAY'S ASTRO ON TAP TO TOMORROW, TUESDAY NOVEMBER 18. SAME TIME SAME PLACE!

How can we build a star here on Earth? How does the fourth state of matter, plasma, behave? Join us TUESDAY, NOVEMBER 18 at 7:30PM as we discuss these topics and more at our next Astronomy on Tap. This week, we are collaborating with plasma physicists from around the country for a special series of Astronomy on Tap events! We'll host two ~20 minute talks, Q&A, and then follow it up with interactive, astronomical pub trivia, and guided stargazing with telescopes!

7:30 p.m. - Dusty Plasma: From Fusion to the Rings of Saturn
8:30 p.m. - Using Magnets to Build a Star on Earth
9:00 p.m. - Astro-themed Pub Trivia Answers and Prizes

About the Series

Astronomy on Tap is a global 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. We host these free events which are open to all at the outdoor patio of the Dog Haus Biergarten in Old Town Pasadena (with inexpensive parking structure one block away).

Each event consists of two ~20-minute informal science talks given by researchers in astronomy, physics, and space science followed by Q&A. In the intermission periods, we have guided stargazing with telescopes, and astro-themed pub trivia. Event is free and open to all. No reservations necessary. For more information and recordings of past events, please see the Caltech Astro Outreach website and the Caltech Astro YouTube page.
