From the Wikipedia entry on British physicist Andrew Lyne → “Andrew Lyne and Matthew Bailes thought that they had made a remarkable discovery in 1991, when they reported that they had discovered a pulsar orbited by a planetary companion; this would have been the first planet detected around another star. However, after this was announced, the group went back and checked their work, and found that they had not properly removed the effects of the Earth’s motion around the Sun from their analysis, and, when the calculations were redone correctly, the pulse variations that led to their conclusions disappeared, and that there was in fact no planet around PSR 1829-10. When Lyne announced the retraction of his results at a meeting of the American Astronomical Society, he received a standing ovation from his scientific colleagues for having the intellectual integrity and the courage to admit this error publicly.”
