The city’s only major observatory offers visitors a chance to see the southern skies through modern and historic telescopes. The best time to visit is during the night on a guided tour, when you can take a close-up look at the stars and planets. During the day, the 3D theatre, in which you seem to zoom through the stars, is worth seeing. It runs at 2:30, 3:30, and 4pm Mondays to Fridays; 11am, noon, and 2:30 and 3:30pm on weekends; and daily during school holidays. Ninety-minute night tours start at 6:15pm and 8:15pm April to September; 8:15pm October and November, and February and March; and 8:30pm December and January. Schedules are subject to change, so check the times when you book your tour. The planetarium and hands-on exhibits are also interesting. Daytime admission to the gardens and the exhibitions is free, but doesn’t include the telescope towers, telescope viewings, and 3D theatre. For A$300 you also can name a star after yourself or someone you love!
