Chabot Space & Science Center

Chabot Space & Science Center is a hands-on astronomy museum, research observatory, and the official NASA Ames Visitor Center located at 10000 Skyline Boulevard inside Robert Sibley Volcanic Regional Preserve and Redwood Regional Park in the Oakland Hills of Oakland, California. Founded in 1883 as the Oakland Observatory through a bequest from hydraulic engineer and philanthropist Anthony Chabot, the institution relocated from downtown Oakland in 1915 and opened its current 86,000-square-foot campus along the crest of the East Bay ridge in 2000. Sitting at 1,500 feet above sea level surrounded by second-growth coast redwoods, the complex combines three historic large-scale research telescopes, a 70-foot full-dome digital planetarium, and interactive aerospace galleries that place visitors directly into the role of space researchers.

What to Expect at Chabot Space & Science Center

A visit to Chabot Space & Science Center divides cleanly between indoor exhibition halls, immersive planetarium screenings, and outdoor rooftop observation decks. Inside the main building, the centerpiece is the NASA Ames Visitor Center and its flagship exhibition, The NASA Experience, which showcases artifacts, wind-tunnel models, rover prototypes, and STEAM challenges developed at NASA’s Ames Research Center in Silicon Valley. Nearby galleries include Going the Distance, examining human exploration across the solar system, Astrolight, which investigates the physics of light and spectroscopy, and Shared Sky: Photos of Our Universe, an astrophotography showcase captured by regional astronomers.

On the outdoor observatory deck, three domed telescopes anchor the center’s 140-year astronomical heritage. During daytime operating hours, staff astronomers conduct safe solar viewing sessions looking at sunspots and solar prominences, while Friday and Saturday evenings bring free public telescope viewings (weather permitting) where guests peer directly through historic refracting and reflecting instruments at planets, star clusters, and nebulae. General admission covers all indoor exhibits and two planetarium shows per day inside the 241-seat theater, which utilizes a Zeiss Universarium star projector paired with a high-definition digital dome system.

• The NASA Experience (NASA Ames Visitor Center): An interactive aerospace gallery where visitors step into the workflow of NASA scientists through real mission hardware, lunar and Martian exploration modules, and hands-on engineering stations.
• Three Historic Research Telescopes (Leah, Rachel & Nellie): The observatory deck houses Leah (an 8-inch Alvan Clark refractor built in 1883), Rachel (a 20-inch Warner & Swasey refractor built in 1914, the largest refractor in the western United States regularly open to the public), and Nellie (a 36-inch Cassegrain reflector housed under a rolling-roof observatory).
• 70-Foot Full-Dome Planetarium: Included with daytime admission, the dome theater screens daily live sky lectures and fulldome films covering black holes, exoplanets, and seasonal constellations over the San Francisco Bay Area.
• Going the Distance & Astrolight Galleries: Permanent exhibitions detailing the engineering milestones required for deep-space travel alongside optical experiments demonstrating how astronomers decode starlight.
• Observation Deck & Redwood Trail Access: Elevated outdoor plazas connect the telescope domes with an enclosed courtyard and direct trailhead steps leading into the shaded canopy of Redwood Regional Park.

Visiting Tips, Getting There & Nearby Pairings

To maximize your daytime visit, arrive near the 10:00 AM opening on Friday, Saturday, or Sunday and check the daily planetarium schedule at the admissions desk first so you can build your gallery walk around two different showtimes. If you plan to attend the free Friday or Saturday night telescope viewings (7:30 PM to 10:30 PM), check the Observatory Weather Details page on chabotspace.org before driving up the hill, as coastal fog or high humidity will close the telescope domes, and dress in warm layers even in summer since ridge temperatures drop rapidly after sunset. Public transit does not serve this section of Skyline Boulevard directly on weekends; visitors arriving via the Fruitvale or Rockridge BART stations should take a rideshare or drive via Highway 13 to Joaquin Miller Road, parking for free in the three-story concrete parking structure right next to the center.

The entire museum complex is wheelchair and stroller accessible, featuring step-free paved paths from the parking structure, wide automatic entry doors, passenger elevators connecting all three exhibition levels and the outdoor observatory deck, and accessible restrooms and theater seating. Because the campus sits inside the East Bay Regional Park District corridor, it pairs naturally with a hike along the West Ridge and French Trails in adjacent Redwood Regional Park immediately outside the parking garage. Less than five minutes south by car along Skyline Boulevard sits Joaquin Miller Park, featuring the historic Abbey landfill monument, Woodminster Amphitheater, and panoramic overlooks of downtown Oakland and San Francisco Bay, while the Montclair Village dining district—lined with coffee roasters, bakeries, and casual family restaurants along Mountain Boulevard—is a 10-minute drive down the hill.

Frequently Asked Questions

What are the operating hours at Chabot Space & Science Center?

Daytime galleries and planetarium shows operate Friday through Sunday from 10:00 AM to 5:00 PM, while the museum is closed Monday through Thursday except for scheduled school field trips and special events. On Friday and Saturday nights, the outdoor observatory deck opens for free public telescope viewing from 7:30 PM to 10:30 PM, weather permitting.

How much do tickets cost and are planetarium shows included?

Daytime general admission is $24 for adults and $19 for youth (ages 2–12), seniors (65+), and college students with ID, while children under 2 enter free. General admission includes full access to the NASA Ames Visitor Center exhibits, daytime solar viewing, and up to two planetarium shows; ASTC Passport Program reciprocal discounts and Museums for All (EBT) reduced admission are also honored.

How much time should I budget for a visit?

Most visitors spend 2.5 to 3.5 hours exploring the interactive exhibits in The NASA Experience, watching one or two 35-minute planetarium shows, and touring the three telescope domes on the observation deck. If you combine your museum ticket with a redwood walk on the adjacent East Bay Regional Park trails, budget half a day.

Is Chabot Space & Science Center accessible and family-friendly?

Yes, the facility offers designated accessible parking spaces in the adjacent garage, elevator access to all exhibition floors and the rooftop observatory deck, wheelchair seating in the planetarium, and sensory-friendly resources. Its hands-on NASA engineering stations, touchable meteorites, and interactive design challenges are geared toward children, teens, and adult space enthusiasts alike.
