Tamil Nadu is a state in South India that is known for its rich culture, heritage, and natural beauty. One of the most fascinating and lesser-known attractions of Tamil Nadu is the Kodaikanal Solar Observatory, a solar observatory owned and operated by the Indian Institute of Astrophysics.
The observatory is located on the southern tip of the Palani Hills, about 4 kilometers from Kodaikanal, a popular hill station and tourist destination. The observatory was established in 1899 as a solar physics observatory and is the oldest and highest optical observatory in India. The observatory is also one of the few places in the world where you can observe the sun and its phenomena in detail and learn about the history and science of solar research.
Kodaikanal Solar Observatory has several features and attractions that make it worth visiting
The Coelostat: The coelostat is a device that consists of two mirrors that reflect sunlight into a fixed telescope. The coelostat was installed in 1904 and is still in use today. It is one of the largest coelostats in the world, with a diameter of 62 cm.
The Spectroheliograph: The spectroheliograph is an instrument that records images of the sun in different wavelengths of light.
The Kodaikanal Tunnel Telescope: The Kodaikanal Tunnel Telescope (KTT) is a modern telescope that was installed in 1989. It is located in a tunnel that is 150 meters long and 6 meters wide. The tunnel protects the telescope from wind and temperature fluctuations. The KTT has a diameter of 15 cm and uses a CCD camera to capture images of the sun.
The Kodaikanal Solar Observatory Museum: The museum is located in a building that was once the residence of John Evershed, a British astronomer who worked at the observatory from 1906 to 1923. The museum displays various historical instruments, photographs, archives, and models related to solar research.
The Kodaikanal Solar Observatory is open to visitors from Monday to Friday, from 10 am to 12 pm and from 2 pm to 4 pm.
