Astronomy on Tap San Francisco – September 2026

Local astronomers talking about stars, planets, and the universe at your neighborhood bar. No PhD required.

Tickets here.

Astronomy on Tap is is a free public lecture series where astronomers give short, laid-back talks over drinks at local bars. No background in science required — our scientists share cool stuff about space while the audience sits back and relaxes, with plenty of time to indulge their curiosity and ask whatever questions they want.

This month, we’re hosting:

John Franklin Crenshaw (Stanford)**–**Before the Big Bang: Inflation and the Multiverse

and

Simon Steel (SETI Institute) – How We (Almost) Discovered ET

Crenshaw is a a Rubin Postdoctoral Fellow at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) at Stanford University. Steel is Deputy Director of the Carl Sagan Center for Research at the SETI Institute and Principal Investigator of the NASA Community College Network.

Astronomy on Tap takes place in cities all over the world. This is a revival of the San Francisco chapter, which regularly hosted events before the pandemic. We’re excited to be back on a monthly basis!

The event is free, but there is a 1 drink minimum. Food (tacos or banh mi) will be available with vegetarian options.
