A British amateur astronomer has broken a 36-year-old record for the number of exploding stars discovered by one person. Retired telecoms engineer Tom Boles, of Coddenham, Suffolk, has photographed and identified 125 supernovae erupting in distant galaxies from his private observatory.
The previous record was held by a professional scientist, Bulgarian-born Professor Fritz Zwicky, who studied the size and age of the universe at the California Insitute of Technology. He found 121 of the suicidal stars before his death in 1974.
Tom, 65, a former president of the British Astronomical Association, operates three computer-controlled telescopes from his countryside site which is unhampered by light pollution. He has been searching for supernovae since 1996 and monitors 12,000 galaxies, working every clear night.
Tom told Skymania News: I hadn’t really appreciated the significance of the achievement when it happened. I was aware of Zwicky’s tally but not that it held any other significance than that it was the achievement of a great man. He died a year after his final discovery. Had he lived longer his tally would no doubt have been much greater.
“The greater part of my achievement comes from the fact that it was done from the UK with its poor, damp, irregular and difficult to predict weather conditions.
“Also, unlike the larger professional efforts of Zwicky, the funding for the effort was entirely private. Around half a million images have been taken to make the discoveries and so accruing over 300,000 hours observing time.”
Supernova discoveries are important to professional astronomers because Type IA blasts can help give precise distances for galaxies and so help to determine the size of the universe. They have been detected by professionals as far away as 11 billion light-years. You can read more about Tom’s observatory and equipment here.
Skymania News told last night of a new Galaxy Zoo project to allow computer users to detect supernovae even if they haven’t got a telescope!
