In the school holidays, I was lucky enough to go and visit “The Dish” in Parkes.
The Dish is a radio telescope that has been being used to study space since 1961.
For more information have a look at this link.
At the CSIRO Observatory you can see The Dish itself from the outside, test the “Whisper Dishes” out the front and watch some terrific 3D films in the cinema inside the Visitors Center.
There is also a terrific coffee shop for the grown ups!
