Vishnu’s affair with the stars started one summer night when there were regular power cuts in his hometown, Sullurpeta, in Andhra Pradesh. He and his elder sister, Bindu, would come out in the front yard and look at the night sky filled with thousands of stars. He was eight years old then; and he would place his head on his sister’s lap while she pointed the different constellations to him.

On those nights, Bindu often said to him: “If you have a telescope you can see all these stars and planets big and bright. You can discover many new things.” Later, when the sun would rise, he would spend hours drawing constellations and rockets on his slate. “Sullurpeta is about 20 km from Sriharikota, the place where all our rockets are launched from,” Vishnu says with much enthusiasm.
When Halley’s comet came around in 1986, his parents read him accounts of observations by a lecturer in Coimbatore published in the local newspaper (The Hindu). This sparked an interest in comets and small bodies in Vishnu’s mind.
When he was in Class 11 he approached a local telescope-maker, also a teacher, Professor Devdas. “I first wrote to M/S Gorandas Desai, official agents of Carl Zeisis Telescope, but the price was exorbitant.” His father could only afford a local telescope. Weeks before the telescope arrived, Vishnu made The Space Centre Library (in Sriharikota) his second home, devouring books on all aspects of astronomy. “It was here I read my first Sky and Telescope and Astronomy issues.”
But he learnt how to see the night sky from Prof. K. Sakthivel, the same physics teacher in the PSG College, Coimbatore who had observed Halley’s comet. Vishnu was studying Filmmaking then at GRD College of Science, which was about 5 km from PSG. “On many weekends we used to travel to distant mountain tops to observe the sky. Those were some of the best days of my life as an amateur astronomer.”
He came to New Delhi to become a journalist. “I joined the Asian Age as a Sub-editor.” And in no time, he joined the Amateur Astronomers Association of Delhi (AAD) and began frequenting the Nehru Planetarium, New Delhi.
Then in 2000, he met Professor Tom Gehrels of University of Arizona for an article he was doing for his paper. “But what came out of the interview was more than just a front-page article. It changed the course of my life.”
On his way back to the hotel, Professor Tom Gehrels told Vishnu – they were in the same cab – that there was little research being done on asteroids in India. Vishnu was fascinated with asteroids and comets “as they are the only cosmic objects (apart from the Sun) that can affect life on Earth in a human life time.”
Vishnu decided to set up an observatory in India to do an extensive research on asteroids, but despite his efforts he could not. “I neither had CCD nor a good telescope.” But impressed with his dedication, Gregg Paris, California-based, veteran amateur astronomer and a retired USAF pilot, bought him a telescope which was then shipped to India. Though Vishnu managed to pay back Paris, he was left with little money. “I could not afford to buy a CCD.”
Almost defeated by his efforts, quite
suddenly he decided to participate in a summer workshop on astronomy in
Arizona in July 2002. With the help of internet friends, and with little money, he reached Tuscan, a desert town in Arizona (US) “which has 300 clear night skies
in a year.”
“I visited well-known asteroid-hunter Roy A. Tucker of Arizona, whom I knew again through Yahoo!” After seven relentless nights, on July 4 Vishnu discovered an asteroid. He named it Bharat. And on one such summer night, many years ago, Vishnu’s sister had said that one day he would discover new things in the sky. Perhaps this was written in his stars.
Now Vishnu is doing his PhD in planetary sciences from the University of North Dakota focusing on composition of asteroids that threaten the Earth. From searching researching, is a long but exciting journey for Vishnu.
