The Tamil Nadu Science and Technology Centre (TNSTC) is a science museum and educational institution in Chennai, India. Established in 1983, it operates under the Government of Tamil Nadu's Department of Higher Education.[2] The centre serves as a hub for science education and awareness, housing several major facilities including the Periyar Science and Technology Centre, the B. M. Birla Planetarium, and various specialized galleries.[3]
The centre is located on the Gandhi Mandapam Road in Kotturpuram, adjacent to the Central Leather Research Institute campus.[4] It lies in the predominantly wooded Adyar-Guindy region known as the Green Lungs of Chennai. The nearest railway station is Kasturba Nagar MRTS, located about 1 km from the centre.
The Tamil Nadu Science and Technology Centre was established in 1983 with financial assistance from the Government of Tamil Nadu. In 1988, the Periyar Science and Technology Centre was inaugurated as a major component of TNSTC, along with the B. M. Birla Planetarium.[5]
In 2007, the centre expanded with the addition of the Solomon Victor Heart Museum.[6] The museum was inaugurated on January 19, 2007, by Union Minister T.R. Baalu, featuring 'A Journey Through Time' exhibition in coordination with the Golden Heart Foundation, Chennai.
The Periyar Science and Technology Centre, operational since 1988, is the main exhibition complex within TNSTC.[2] It houses multiple galleries and interactive exhibits focused on various aspects of science and technology.

The B. M. Birla Planetarium, inaugurated in 1988, is a major component of TNSTC.[8] The planetarium features a 15-meter dome and seats 250 visitors.

The planetarium conducts regular shows in Tamil and English about astronomy and space science. Shows include topics such as the Solar System, sky and seasons, eclipses, Earth, Moon landing, comets, meteoroids, stellar cycle and the deep sky.
