Siding Spring Observatory

Siding Spring Observatory (SSO), on the edge of the Warrumbungle National Park near Coonabarabran, NSW, is Australia's premier optical and infrared astronomical observatory.

Since opening in 1964, The Australian National University has operated the observatory site hosting research telescopes from the ANU's Research School of Astronomy and Astrophysics (RSAA), the Australian Astronomical Observatory (AAO), Las Cumbres Observatory (LCO) and many other institutions from around the world at this spectacular location next to the picturesque Warrumbungle National Park.

Research caried 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. Nearly every night there's something new being done, and new discoveries being made.

You can learn more about the various telescopes and the organisations that own and run them on the telescopes of SSO page, or click on any of the logos below to be taken directly to the organisations website.

Siding Spring Observatory is a proud supporter and close neighbour of the Warrumbungle National Park - designated in 2016 as Australia's first Dark Sky Park by the International Dark-Sky Association (IDA).

An IDA International Dark Sky Park (IDSP) is a land possessing an exceptional or distinguished quality of starry nights and a nocturnal environment that is specifically protected for its scientific, natural, educational, cultural heritage, and/or public enjoyment.

The Gold Tier status of the site acknowledges the Warrumbungle National Park's pristine skies and reputation as an outstanding place to view the stars unfettered by the light pollution that affects Australia's cities.

Warrumbungle National Park joins other international parks such as Death Valley National Park in the United States and Galloway Forest Park in Scotland as officially designated Dark Sky Parks.
