Chabot Space and Science Center, located in Oakland, California, is a hands-on center featuring interactive exhibits, digital planetarium, large screen theater, hands-on activities and three powerful telescopes.

The Center is the continuation and expansion of a public observatory that has served San Francisco Bay Area schools and citizens with astronomy and science education programs for over 123 years.

[edit] History

The sign at the entrance of the Chabot Space and Science Center.

The institution began in 1883 as the Oakland Observatory, through a gift from Anthony Chabot to the City of Oakland.^[1] The original Oakland Observatory was located in downtown Oakland, and provided public telescope viewing for the community. For decades, it also served as the official timekeeping station for the entire Bay Area, measuring time with its transit telescope.

The observatory moved to its Mountain Boulevard location in 1915 due to increasing light pollution and urban congestion. In the mid-1960s, the facility was expanded considerably. Throughout this time, the Chabot Science Center, as it was renamed, was staffed mainly by Oakland Unified School District personnel and volunteers. In 1977, seismic safety concerns terminated public school students’ access to the original observatory facility. The observatory building remained open to the general public, but school activities were limited to outlying classroom buildings and the planetarium.

Recognizing the need to restore full access to the facility, either by repair or relocation, in 1989 Chabot Observatory & Science Center was formed as a Joint Powers Agency with the City of Oakland, the Oakland Unified School District, and the East Bay Regional Park District, in collaboration with the Eastbay Astronomical Society, and in 1992 was recognized as a nonprofit organization. The project broke ground in October 1996 and construction of the new Science Center began in May 1998.

In January 2000, anticipating the opening of the new facility, the organization changed its name from Chabot Observatory & Science Center to Chabot Space & Science Center. The new name was chosen to better convey the organization's focus on astronomy and the space sciences, while communicating both the broad range and the technologically advanced nature of programs available in the new Science Center.

Opened August 19, 2000, the new Chabot Space & Science Center is an 86,000-square-foot, state-of-the-art science and technology education facility on a 13-acre site in the hills of Oakland, California.

[edit] Telescopes

Chabot Space and Science Center has three telescopes. "Leah" is an 8" refractor telescope was built in 1883 by Alvan Clark and donated by Anthony Chabot.^[2] "Rachael" is a 20" refractor telescope commissioned in 1914 from Warner & Swasey, with optics by John Brashear.^[3] It is the largest refractor in the western United States regularly open to the public. "Nellie" is a 36" reflecting telescope which opened in June 2003 and is housed in a rolling roof observatory.^[4]

[edit] Attractions

Aside from its telescopes, it contains:

the Ask Jeeves Planetarium, a "full dome digital projection system" with various shows running daily.^[5]
the Tien MegaDome Theater, a 70-foot dome screen auditorium with various shows running daily.^[6]
the Challenger Learning Center, a hands-on simulated space mission where 8 teams work together to complete a mission.^[7]
Many changing exhibits that highlight space and science topics. As of August 18, 2006, there are nine open exhibits.^[8]
