You are also invited for a relaxing coffee or lunch taking in the wonderful views from the café.  Contact the café on (02) 6125 3634.


The Visitor Centre has something for everyone with science exhibits, a kids zone and info about Mount Stromlo’s rich history of tragedies and triumphs.

There’s also a heritage trail with augmented reality to transport you to a different time as you stroll past kangaroos while taking in the sweeping views across Canberra and the surrounding mountains.

Visitor Centre

The Visitor Centre exhibits feature not only Astronomy but world-class research from across ANU. It is unstaffed, but you may find a volunteer at the Ask a Scientist desk. It is open 9:00 AM - 3:30 PM on weekdays and 9:30 AM - 4:00 PM on weekends. Entry is free.

The building is open daily from 9:00 AM - 5:00 PM and features innovative audiovisual displays about Mount Stromlo's history, scientific achievements and the impacts of the fire events on site. For more information, click here.

Mount Stromlo Observatory site tours

Alternatively, guide yourself along the Mount Stromlo Heritage Trail. The Heritage Trail includes 12 interpretive signs which together provide a comprehensive history of Mt Stromlo Observatory. Download the ANU Space app to enrich your walk. 

Night school visits

School visits begin with a 3D astronomy movie as an introduction. The main part of the evening is a stargazing session using Mount Stromlo's outreach telescopes. To complete the evening there will be a Question & Answer session with professional astronomers.

We currently run programs suitable for primary school students as well as Year 10, 11 and 12 physics students with group sizes between 15 and 40 students.

For more information or to arrange a date for your school to participate, please contact us by email.


Please note that the actual objects observed will depend on the scheduled date and that in the event of cloudy weather, either an alternative program (including a tour of the observatory) can be run or the session rescheduled.
