The Sir Thomas BrisbanePlanetarium is located on the grounds of the Brisbane Botanic Gardens in the suburb of Mount Coot-tha, Brisbane, Queensland, Australia. The Planetarium was officially opened on 24 May 1978. The Planetarium is named after Sir Thomas Brisbane, governor of the colony of New South Wales and well known Scottish astronomer who established the first significant observatory at Parramatta, Australia, in 1822 for mapping the southern skies. The Planetarium is located about from the Central Business District, and is administered by the Brisbane City Council. The Planetarium features the 12.5m diameter Cosmic Skydome with a maximum concentric seating capacity of 130. Extensive space exploration and astronomy displays in the Planetarium's Foyer and Gallery include the 1969 Apollo 11Moon landing with a replica of Neil Armstrong's space suit and a 1/48th-scale Saturn V rocket, meteorites, and numerous models of spacecraft, rockets, and astronomical instruments. In 2018, a major permanent exhibit - Skylore: Aboriginal and Torres Strait Islander Astronomy - was installed in the Gallery. The original Zeissstar projector was removed from the Cosmic Skydome during the upgrade in 2010 and was placed on display in the foyer in early 2012. A replacement optical star projector by Ohira Tech was installed in the Cosmic Skydome in early 2013. A mini-theatre usually features a regularly updated Space Telescope Science Institute web feed. An observatory contains a permanently mounted Zeiss 15 cm refractor and a Meade 25.4 cm "Go To" Schmidt-Cassegrain telescope. The Planetarium runs more than 1,300 regular shows per year in the Cosmic Skydome for public and school groups, and observing sessions in the observatory. During Financial Year 2017/2018, the Planetarium had more than 155,000 visitors with nearly 80,000 attending sessions in the Cosmic Skydome. A major upgrade for the Planetarium was completed in June 2019 with a new digital projection system installed. Adding to the new Skylore Story a world first, The exhibit features some of Australia's leading Aboriginal and Torres Strait Islander Elders sharing their star knowledge for the first time. The content within this exhibition was sourced and curated by Dr Duane Hamacher, an astronomer and academic working closely with Aboriginal and Torres Strait Islander communities.
