OUR VISION

We acknowledge that the Anglo-Australian Telescope (AAT) cannot directly compete with the latest generation of optical telescopes overseas. However, we strongly oppose an unmanaged wind-down that neglects the heritage, the instrument, and the regional economy, including our local dark sky initiatives. Instead, we are advocating for a practical, managed transition that supports stargazing events while ensuring we save Siding Spring, built on four clear pillars.

The Four Pillars

Solar System Drive

The Solar System Drive already exists along five scenic routes that converge at the AAT, serving as a testament to dark sky initiatives aimed at enhancing stargazing events in the area. Scaled planet billboards transform the journey to Siding Spring into a signature visitor experience. This initiative is primed to be further refreshed, promoted, and utilized at low cost — a working demonstration of the Dark Sky Hub and a community approach to increase visitor numbers.

Community Interface

A small community entity is proposed that serves as a bridge between the scientific facility and the public, it embodies the Dark Sky Hub identity. This organization manages the website and marketing, coordinates various dark sky initiatives, and can help oversee the Solar System Drive. Additionally, it provides a full-time liaison with a dedicated Dark Sky focus to ensure that local operators, visitors, and the site have a clear point of contact for stargazing events.

Town Presence

A Dark Sky Hub office and visitor centre in Coonabarabran is proposed that aims to support dark sky initiatives and features a planetarium as a short-term goal. This indoor, all-weather experience is designed for families, schools, and travellers, providing an alternative when cloud cover limits stargazing events. The initiative also complements existing local businesses.

Observatory Visitor Experience

To better reflect the world ranking of the Dark Sky Park a quality café and interpretive museum at the foot of the AAT building, with beautiful views of the Warrumbungles is required. 

This will be a critical interface between the science and the public showcasing the area, heritage and the scientific work.

A practical pathway, not a default close-down

These four pillars form a realistic hybrid model — residual science capability, protected heritage, education, and a visitor experience that can help fund ongoing care of the site.


Using what we have now, energise and expand small pocket sized experiences, corporate functions/conferences and education visits.


As the vision grows introduce scale with the cafe concept overlooking the Warrumbungles at the observatory apron. is the vision future we are working toward.

Explore the world’s largest virtual solar system, stretching from Pluto to the Sun. Scaled billboards along five scenic routes transform the journey to Siding Spring into an unforgettable educational adventure, showcasing dark sky initiatives and promoting upcoming stargazing events to help save Siding Spring for future generations.

OPEN THE DRIVE

Connecting Country, the Solar System and Our Dark Sky

The Solar System Drive is the world’s largest virtual solar system, offering an educational and tourism journey right here in New South Wales. Formally opened in 2008, it features scaled 3D billboards of the Sun and planets along five scenic routes that beautifully converge at the Anglo-Australian Telescope (AAT) located at Siding Spring Observatory. This site is the heart of Australia’s first International Dark Sky Park, which is part of broader dark sky initiatives aimed at preserving our night sky near Coonabarabran. 


Download your free guide below and make the drive an unforgettable part of your adventure. It’s the perfect opportunity to explore stargazing events along the way and appreciate the brilliance of the cosmos.

Where we are tonight

The kitchen table

Think of our galaxy as the kitchen table. The bright centre is the bowl in the middle. Our Sun is a grain of salt out toward the rim. Earth is a speck going around that grain once a year. Night, especially under initiatives like those to save Siding Spring, represents the way you face when your back is to the lamp. Out the front door, you see the city; out the back door, you see the paddock. It’s the same house but a different night, perfect for stargazing events.

Enter the Sky

Summer · out the back door

From December to February, during the warm, clear nights, we gaze out past Orion toward the edge of our galaxy, where the stars are beautifully spread out. The Drive is pleasant in daylight, but we encourage you to come back in winter. Stand beneath our Milky Way core, high overhead, and experience stargazing events that celebrate dark sky initiatives aimed at preserving our celestial views and helping to save Siding Spring.

Autumn · turning for home

Winter · out the front door

March to May. We have turned and are travelling inward again. More stars join us in the night as we embrace dark sky initiatives. Our Milky Way begins to thicken, inviting us to participate in various stargazing events. Nights get longer and cooler. The first big break after Christmas and the Easter holidays is a good shoulder season to save Siding Spring and enjoy the beauty of the cosmos.

From June to August, Earth sits between the Sun and our galactic core, providing amazing opportunities for stargazing events. As we look into the night sky, we see tens of thousands of light-years of stars, a breathtaking blend that forms the milk in the Milky Way. In winter, Coonabarabran offers a prime view as our galactic core stands high above. By participating in dark sky initiatives, we can help preserve these stunning views and support efforts to save Siding Spring. Just stand under our galaxy and bathe in its wonder.

From September to November, as we look out through a thinner part of our galaxy disc, the Magellanic Clouds shine brightly, creating perfect conditions for stargazing events. With great travelling weather, the flower season blooms, offering a treat for birdwatchers and highlighting the importance of dark sky initiatives to preserve our celestial view while we enjoy the beauty of nature. Let’s not forget to save Siding Spring to ensure the night skies remain unspoiled for generations to come.

What's Up · Spring 2026

A one-minute walk through the spring sky from Coonabarabran. Early in the season the Milky Way still stands overhead, then it rolls west. Look for Dschubba, the hot white star in Scorpius, Omega Centauri in binoculars, and through a telescope Messier 83 (M83) the Southern Pinwheel, the Trifid Nebula in Sagittarius, and the Helix Nebula as a spring extra. Use the Calendar for dark nights and moon phase. Weather still decides the night.
