History
Facilities
- Hale Telescope: The 200-inch (5.08 meters) Hale Telescope, named after George Ellery Hale, was the largest telescope in the world from its completion until 1976. It has contributed significantly to astronomy, including the discovery of quasars.
- Other Telescopes: Besides the Hale, Palomar houses several other telescopes:
- Samuel Oschin Telescope, a 48-inch Schmidt camera used for surveys.
- The 60-inch telescope, which was the second largest telescope in the world when it was built.
Scientific Contributions
- Deep Sky Surveys: The Palomar Sky Survey, which used the Samuel Oschin Telescope, provided one of the most extensive photographic maps of the night sky.
- Discoveries: Notable discoveries include the first brown dwarf star, many new asteroids, and significant contributions to the understanding of quasars and galaxy formation.
Current Status
- The observatory continues to be a leading research facility, though its role has shifted with the advent of newer, larger telescopes elsewhere. It still plays a crucial role in training astronomers, testing new instruments, and conducting specific observational programs.
- Public Access: The observatory offers tours and public viewing nights, making it a popular destination for both amateur and professional astronomers.
