The Sir Thomas Brisbane Planetarium was established in 1978 by Brisbane City Council. Located within Brisbane’s Mt Coot-tha Botanic Gardens, the Planetarium is home of the Cosmic Skydome, a 12.5-metre-diameter projection dome.
Enjoy a show in the Cosmic Skydome, take a tour of Brisbane’s current night sky with one of our astronomers or visit the Planetarium’s Display Zone to take an astronomical journey from the present day Solar System to the time of the Big Bang.
