February 28 is celebrated as the “National Science Day” in India! This is to commemorate the discovery of the “Raman effect” by Sir C.V. Raman on 28 February 1928. The 01-March-13 newspapers carried a tiny news article on this, the larger sections being devoted to the Railway and Union Budget news. After all in a nation of a billion people and its billion challenges, science often takes a backseat.
However, the last weekend of February, I had a close brush with science like no other. My father who was formerly a senior scientist at Indian Institute of Astrophysics had promised a family outing to the IIA VBO Observatory at Kavalur, near Vanaimbady, TN located at a distance of 170Km from Bangalore. The observatory is devoted to studies in inter-stellar and deep-galactic research and studying of stellar activity and star’s life cycle.
We started early on Saturday morning, and were pleasantly surprised by a thick mist that engulfed the empty streets, e.s.p the Electronics City expressway, which presented an eerie sight. The ride from Bangalore to Vaniambady is effortless, the roads are wonderfully maintained, but multiple toll-booths on the route play spoilsport. However when we reached the IIA campus, its well maintained lawns and office buildings was a welcome sight.
And not to forget the awesome views of the Telescope buildings. The observatory houses Asia’s largest optical telescope (2.3m lens!!) and many other smaller telescopes. The Kavlur observatory started operation in late 1970’s and the sleepy and quiet town offers clear skies and ideal conditions during much of the year, making it an apt site for observing the night sky for deep space research.
Its love at the first sight , the first look at the 2.3m telescope building! The building not only houses the gigantic telescope, but also electronics labs, optical labs, control rooms, libraries and "guest-rooms” for the scientists to stay after a night long ‘observation’ slot. This 2.3m (90inch) telescope is fully “Made In India” and commissioned in 1986 by the then P.M. Rajiv Gandhi.
We stayed at the 1m (40inch) telescope which first started operation in 1972 and has been the main stay of extensive scientific research in the field of astrophysics in the last 40years in India. The beautiful structure is an imposing sight.

And lo the actual 1m telescope itself
We spent the evening gazing at the night sky, and thousands of bright twinkling stars greeted us on a dark clear sky. The observatory campus and surroundings are designed to reduce lighting in the buildings (by the usage of shades etc.) which can impact the sensitive instruments. All in all, one gets the eerie feeling of walking around Jurassic Park! The Observatory is located in a jungle area and pythons, cobras, deer and elephants are visitors to the campus too, keeping the scientists in “lively” company. Of late, the electrified fencing keeps some of these unwanted visitors outside the gate!
We viewed Jupiter, Moon and Sirius (brightest star in the night sky) using the telescope. The gas bands in the Jupiter’s atmosphere, its 4 closest satellites, craters on the Moon could all be very clearly seen. Its hard to imagine how the clean disk of the moon when viewed directly turns out to be a scarred and cratered surface when viewed with a telescope (almost resembles a golf ball!)
After an evening in the company of “stars” we departed for Bangalore. As i sat in the office bus on Monday morning, i could not help but think how our daily life revolves around bugs, meeting, traffic-jams and other little worldly worries when a fantastic universe exists right above holding billions of stars, galaxies, and even possibly intelligent life outside!. Its creepy even to think that they might just be observing us on Earth using advanced high resolution telescopes !
