Nestled in the scenic hills of Oakland, California, the Chabot Space and Science Center is not just a place for stargazing—it’s a living testament to the city’s long-standing commitment to science education and astronomy. The institution’s roots trace back to 1883 when it first began as the Oakland Observatory, thanks to the generous donation of Anthony Chabot to the city. This marks the beginning of an enduring legacy in public astronomy and space exploration education.
The Early Days: Oakland Observatory (1883-1915)
The original Oakland Observatory was strategically located near downtown Oakland, offering the public the opportunity to explore the night sky through telescope viewings. It also served as an important hub for scientific measurement, functioning as the official timekeeping station for the Bay Area for decades. During this period, the observatory utilized its transit telescope to measure time, a crucial service for the growing region.
However, as the city of Oakland expanded, the observatory faced challenges from urban development and light pollution. In response, the observatory moved to its current location on Mountain Boulevard in 1915. The new site, nestled in the hills, provided a clearer view of the night sky, making it more suitable for astronomical observations.
Mid-20th Century Expansion and Challenges
By the mid-1960s, the observatory underwent significant expansion to accommodate growing interest and scientific advancements. Throughout this period, the observatory, which had by then been renamed the Chabot Science Center, continued to be supported mainly by volunteers and staff from the Oakland Unified School District.
However, in 1977, safety concerns due to seismic risks led to the suspension of public school programs at the original observatory facility. While the observatory building remained open to the public, school activities shifted to other facilities and the planetarium, which continued to operate independently.
A New Era: Chabot Space & Science Center (1989-Present)
In 1989, recognizing the need for a major upgrade, the Chabot Observatory & Science Center was restructured as a Joint Powers Agency, with the City of Oakland, the Oakland Unified School District, and the East Bay Regional Park District collaborating to safeguard the future of the center. In 1992, it was officially recognized as a nonprofit organization. Under the leadership of Dr. Michael D. Reynolds, the center began major renovations, and by 1996, the groundbreaking for a new 88,000-square-foot Science Center took place.
With construction of the new facility underway in 1998, the institution rebranded itself in 2000, changing its name from the Chabot Observatory & Science Center to the Chabot Space & Science Center to better reflect its expanded focus on astronomy and space sciences. The name change also emphasized the center’s goal of offering cutting-edge programs and experiences to the public. On August 19, 2000, the state-of-the-art facility officially opened its doors.
Today’s Chabot Space & Science Center
Today, the Chabot Space & Science Center sits on a 13-acre site in the Oakland hills, offering an immersive educational experience to visitors of all ages. With its 86,000-square-foot facility, the center continues to inspire and educate the public about space, science, and technology. Although it was once an affiliate of the Smithsonian Institution, the center is now an independent nonprofit organization dedicated to promoting scientific literacy and exploration.

The Observatory: A Place for Stargazing
The Chabot Space and Science Center is home to three major telescopes that remain open to the public on weekends, providing visitors with an opportunity to observe celestial bodies.
- Leah: This 8-inch refractor telescope, built in 1883 by Alvan Clark & Sons, was donated by Anthony Chabot. It remains one of the most historically significant instruments at the center, primarily used for educational purposes.
- Rachel: Commissioned in 1914, this 20-inch refractor telescope is the largest regularly open to the public in the western United States. Made by Warner & Swasey and with optics by John Brashear, “Rachel” is used for both public viewing and educational outreach.
- Nellie: The largest telescope at the center, Nellie is a 36-inch Cassegrain reflector, which opened in 2003. The telescope’s primary mirror was donated by Lawrence Livermore National Laboratory. This telescope is primarily used for research, including tracking Near Earth Objects (NEOs).
Planetarium: A Window to the Cosmos
The Chabot Space & Science Center also boasts a state-of-the-art planetarium. With seating for 250 people under a 70-foot diameter dome, the planetarium is a popular feature for visitors. It offers both live weekly shows and pre-recorded “fulldome” experiences.
The planetarium’s Zeiss Universarium Mark VIII projector, recently refurbished, uses fiber-optic technology to create a stunning, precise view of the night sky, featuring up to 9,000 celestial objects. One of the standout shows is Cosmos 360, which takes viewers on a guided tour of the night sky, offering in-depth views of planets, constellations, and other astronomical events. The show is updated regularly to reflect the seasonal night sky.

Galaxy Explorers Program
Chabot Space & Science Center isn’t just about passive learning—it also offers volunteer and educational opportunities for local teens through its Galaxy Explorers Program. Sponsored by YouthALIVE!, the program provides teens with the chance to engage with visitors as explainers on the museum floor or during outreach trips. This initiative allows young people to gain valuable experience in science communication while fostering a love for space and science in the community.
Conclusion
Chabot Space & Science Center is a beacon of scientific curiosity and education in the Bay Area. Its rich history, spanning over a century, reflects its evolution from a simple observatory to a leading institution in space and science education. Whether through its iconic telescopes, immersive planetarium shows, or community-focused programs, Chabot continues to inspire generations of explorers, scientists, and dreamers. If you haven’t yet visited, now is the perfect time to discover the wonders of the universe right in the heart of Oakland.
