Samuel Oschin Planetarium

Samuel Oschin Planetarium. It is the premier public planetarium theater located within the iconic Griffith Observatory in Los Angeles, California. Opened in 2006 following a major renovation of the observatory, the facility is named for philanthropist Samuel Oschin and represents a state-of-the-art center for astronomical education and immersive celestial shows. It features one of the most advanced star projectors in the world and serves as a key public gateway to exploring the universe.

History

The planetarium's creation was the centerpiece of a $93 million renovation and expansion of the historic Griffith Observatory, which first opened in 1935. The project, led by the City of Los Angeles and a committee chaired by former Mayor of Los Angeles Richard Riordan, began in 2002. Funding was significantly bolstered by a generous donation from the Mr. and Mrs. Samuel Oschin Family Foundation, leading to the facility being named in honor of the aerospace and real estate entrepreneur. The new Samuel Oschin Planetarium opened to the public on November 3, 2006, replacing the observatory's original 1964 Zeiss star projector. This reopening coincided with the observatory's celebration of the career of astronomer Edwin Hubble, whose pioneering work on the expansion of the universe was conducted using the Hooker Telescope at Mount Wilson Observatory.

Architecture and design

Designed by the architectural firm Pfeiffer Partners, the planetarium is a subterranean addition that preserved the historic profile of the original Griffith Observatory building designed by John C. Austin. The 290-seat theater is housed under a 75-foot diameter dome, one of the largest in the United States. The interior employs a steeply sloped, stadium-style seating arrangement to ensure unobstructed views for all visitors. Key design elements focus on creating an immersive environment, with specialized acoustic treatments and a completely dark interior when shows are running. The expansion also included the creation of the adjacent Gunther Depths of Space exhibit hall, which connects thematically to the planetarium's presentations.

Exhibits and programs

The planetarium is not a static exhibit space but a dynamic theater presenting regularly scheduled, professionally produced shows. These narrative programs, such as "Centered in the Universe" and "Water Is Life," explore topics ranging from the Big Bang and the Solar System to the search for extraterrestrial life. The shows are created by the observatory's in-house team of astronomers and educators, often in collaboration with institutions like the California Institute of Technology and the Jet Propulsion Laboratory. Educational outreach is a core function, with special programs for Los Angeles Unified School District students and live, presenter-led tours of the current night sky, connecting the dome's simulations to observations possible with the observatory's own Zeiss refracting telescope.

Griffith Observatory association

The planetarium is an integral component of the Griffith Observatory, which is operated by the City of Los Angeles Department of Recreation and Parks. Its operations are supported by the non-profit Friends Of The Observatory, which helps fund show production, educational initiatives, and technological upgrades. The planetarium's programming is directly aligned with the observatory's founding mission, articulated by donor Griffith J. Griffith, to make astronomy accessible to the public. This synergy makes the entire facility, including the planetarium, a major cultural and educational landmark within Griffith Park, attracting millions of visitors since its reopening.

Notable features and technology

The theater's most notable feature is the custom-built Zeiss Universarium Mark IX star projector, one of the most advanced optical-mechanical projectors ever manufactured. This instrument projects a phenomenally accurate night sky containing over 9,000 stars onto the dome. It is supplemented by a sophisticated, digital, full-dome video projection system from Evans & Sutherland, allowing for seamless transitions from the realistic star field to immersive visualizations of cosmic phenomena. This hybrid technology enables presenters to voyage from the surface of Earth to the outer reaches of the Milky Way or the aftermath of the Cretaceous–Paleogene extinction event. The integrated system is controlled from a central console, making it a versatile tool for both pre-recorded shows and live astronomical exploration.
