After more than a decade of inviting visitors to observe the wonders of our universe, the Phoebe Waterman Haas Public Observatory is now entering a period of revitalization and transformation. While we transform, we are closed to the public. 

In the meantime, you can explore other astronomy programs by visiting our events page.

Astronomy programming is made possible by support from the Thomas W. Haas Foundation, the Otto Haas Charitable Trust, The Waterman Trust, and the Wyncote Foundation.

About Phoebe Waterman Haas

Phoebe Waterman Haas received her doctorate in astronomy from the University of California, Berkeley, in 1913 — one of the first American women to earn such a degree. She also studied at the historic Lick Observatory near San Jose, California. She is believed to be the first woman to directly use the Lick telescope, which with its 36” lens was one of the largest telescopes in the world at that time.
