One Friday night a month, we host a free public lecture on astronomy and space science given by a member of our department. These events consist of a 30-minute science lecture, followed by 90 minutes of guided stargazing with telescopes on the adjacent athletic fields. We also provide an extended Q&A with an expert panel of professional scientists after the lecture. The guided stargazing is contingent on clear weather, but the lecture and Q&A will occur either way.
These events are free, open to all, and held at the level of a layperson with no science background. Children are welcome to join, although some of the material may be a little bit advanced, depending on the topic of the month. No reservations are needed, just show up, and stay for only as long as you want. Stargazing Lectures take place in the Cahill Center for Astronomy and Astrophysics on Caltech's campus. For directions and parking information, see our Directions page.
In addition to being held in person, our Stargazing Lectures and Q&A are live-streamed on our Caltech Astro YouTube channel. You can view photo and recordings of all of our past stargazing lectures going back to 2016. For announcements of our next lecture, visit our Upcoming Events page or follow us on social media.
