The SFAA hosts distinguished guest speakers who are leaders in the fields of astronomy, physics and related disciplines. The speakers present to the public and SFAA members the latest developments from cutting-edge scientific programs.

The lecture series is temporarily on hold while the SFAA Speaker Committee works through the scheduling process of returning to in-person lectures, which will also be live-streamed and posted to our archived lectures.

The April to October Mt. Tam Astronomy Lecture Series, sponsored by the Friends of Mt. Tam, with the SFAA providing public telescope viewing following the lecture, is also being reorganized.
