- Recently it made the celebrations of 50 years of operations.
- This telescope was set up in 1972 by Professor Vainu Bappu at Kavalur, Tamilnadu.
- Kavalur is a village in the Jawadhu Hills in Vaniyambadi taluk, in Tirupathur district.
- The skies above Kavalur were excellent, and its southern location would allow it to see most of the northern and southern skies.
- It has played a significant role in astronomy with major discoveries like the presence of rings around the planet Uranus, a new satellite of Uranus, the presence of an atmosphere around Ganymede which is a satellite of Jupiter.
- It also includes the discovery and study of many ‘Be Stars’, Lithium depletion in giant stars, optical variability in Blazars, and the dynamics of the famous supernova SN 1987A.
- Starting from the Cassegrain photometer and Echelle spectrograph in 1976, the new grating spectrograph in 1978, the fast-chopping polarimeter in 1988 with its replacement in 2016, and the latest NIR photometer in 2021, the observatory has constantly been upgrading its facilities.
