Mount Stromlo Observatory

Mount Stromlo Observatory (MSO) is the home of the ANU Research School of Astronomy and Astrophysics. It's about 18km southwest of Canberra city in the Australian Capital Territory (ACT).

The administrative centre, the offices of the astronomers and students, the mechanical, electronic and optical workshops, and the computer laboratories are located at MSO.

MSO was badly damaged in the 2003 Canberra bushfires, so there are no longer working research telescopes here. All of the telescopes are now located at Siding Spring Observatory. However, the reconstruction of MSO has included the development of the Advanced Instrumentation Technology Centre and rebuilding the heritage Commonwealth Solar Observatory building.

Opening hours

The Visitors Centre and Southern Cross Stromlo Café are open from 9am-4pm on weekdays, 7.30am-5pm weekends.

Mount Stromlo is 18 kilometres southwest of Canberra centre, on Cotter Road, Weston Creek.
