Stardate Chabot

By the Numbers


The Chabot Space and Science Center originally opened in downtown Oakland 125 years ago. The Oakland Observatory, as it was then known, provided a telescope for astronomers to search for new planets and served as the Bay Area’s official timekeeping station. The center eventually reopened in the Oakland hills in an 86,000-square-foot, $84 million home that features three telescopes and a planetarium. A series of celebrations this year mark Chabot’s 125 years, starting with Space Games, a free family fun day on June 21.


Year that Leah, a refracting telescope, was built and given to the Oakland observatory by hydraulic engineer Anthony Chabot.
