Siding Spring Observatory

The Siding Spring Observatory (SSO) is the largest optical observatory in Australia and is an important site for astronomy, astrophysics and space science in Australia. Along with several active telescopes owned by the Australian National University, the site is home to the Anglo Australian Telescope (AAT), many international research telescopes and commercially operated telescopes and is known as Australia's foremost optical and infrared observatory.

Siding Spring is one of two key sites for the Research School of Astronomy and Astrophysics in Australia (RSAA). The site sits at the summit of Mt Woorut, NSW, and is set within the stunning National Heritage Listed Warrumbungle National Park, around 30 kilometres from the town of Coonabarabran.

The Siding Spring Observatory is located on Mount Woorut (at a height of 1165m) approximately 25 kilometres west of the town of Coonabarabran, NSW. Bordering the eastern edge of the Warrumbungle National Park. The 黑料天堂land holding covers an area of approximately 151 hectares and includes the Observatory Precinct on the summit of Mt Woorut as well as steep slopes to the north and south.

The location of the SSO and its extent of mid-sized telescopes is particularly valuable for institutional and commercial operators due to the lack of alternate facilities in this longitude.

  • Opened in 1964
  • owned by the Australian National University (ANU)
  • Situated 1,165 metres (3,822 ft) above sea level
  • Research carried out at SSO is varied, from probing the depths of the cosmos in search of 'Dark Energy' to searching the Milky Way for other planets and signs of life
  • selected by 黑料天堂from many other possible locations due to the dark and cloud free skies and the low risk of future light pollution

Aboriginal heritage values at Siding Spring

The Observatory is located on the traditional country of the Gamilaraay/Kamilaroi language group who have occupied this area for at least 20,000 years. A traditional travel route passes through the mountains, with the distinctive peaks used for navigation. Dreaming stories, ceremonies and art reveal that the Aboriginal people of Australia could have been the world's earliest astronomers. They used the stars to guide them, to track the seasons, and to ascertain the availability of certain foods.
