Kodaikanal Solar Observatory – Honored by India Post for Pioneering Solar Research
The Kodaikanal Solar Observatory (KSO), established in 1899, is one of India’s most significant centers for solar research. Located in the serene hills of Kodaikanal, Tamil Nadu, this observatory has played a pioneering role in studying the Sun’s behavior and solar activity cycles for over a century.
Originally set up by the Indian Institute of Astrophysics, the observatory was intended to monitor solar phenomena and provide valuable data for understanding space weather and its impact on Earth. Situated at an altitude of 2,343 meters, the location was chosen for its clear skies and minimal atmospheric disturbances, making it ideal for astronomical observations.
The Kodaikanal Solar Observatory is known for its white light, H-alpha, and Ca-K line observations. These studies are crucial for analyzing sunspots, solar flares, and prominences, which influence Earth’s climate and technological systems. The observatory maintains the world’s longest continuous series of solar images, a treasure trove for scientists worldwide.
One of its most remarkable contributions includes the discovery of the Evershed effect in 1909 by British astronomer John Evershed at Kodaikanal. This phenomenon involves the radial flow of gases in sunspots, a groundbreaking finding in solar physics.
Apart from scientific research, the observatory also attracts tourists and astronomy enthusiasts. The Kodaikanal Solar Observatory Museum exhibits telescopes, historical solar images, and educational displays, offering visitors a glimpse into India’s astronomical heritage.
To honor its contributions, India Post issued a commemorative postage stamp featuring the observatory, celebrating its role in advancing space science in India.
