Siding Spring Observatory

Siding Spring Observatory is a research facility with multiple telescopes located on Mount Woorut at 1,165 meters (3,823 feet) elevation, with the Anglo-Australian Telescope as its main instrument. The site uses various specialized instruments for scientific observation and data collection.

The Australian National University selected this location in 1962 to move operations away from Mount Stromlo Observatory, where light pollution from Canberra had become a problem. This relocation to the higher mountain site provided better conditions for observation.

The site stands on Gamilaraay Country, where Aboriginal people used the stars for navigation and understanding seasonal cycles over thousands of years. This ancient connection between people and the sky gives the place deep cultural roots.

The facility sits at a remote high-altitude location, so visitors should prepare for changing weather and bring appropriate gear. Access to the site is best when skies are clear, and reaching the complex requires reasonable fitness.

The observatory runs the only comprehensive tracking program in the Southern Hemisphere for near-Earth objects and gamma-ray bursts. This specialized role makes the site an important early-warning station for potential threats from space.
