What does the night sky look like in x-rays and how does it affect us on Earth? What do professional scientists think about the prospect of aliens existing? Join us at 7:30PM PDT, Tuesday, June 16th for a very special Astronomy on Tap to discuss these questions.  Tonight's event will be part of our 10th year anniversary week alongside our City of Astronomy events here in Pasadena, featuring visiting scientists from around the world in town for the American Astronomical Society's semi-annual meeting in Pasadena. This Astronomy on Tap will be one of three happening this week for the City of Astronomy, so stay tuned! 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. - Exploring the X-ray Universe with eROSITA
8:30 p.m. - What We Talk About When We Talk About Aliens
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.
