Andrew Lyne’s Applauded Exoplanet Retraction

In 1991, British radio astronomer Andrew Lyne had electrified astronomy by announcing what he believed was the first planet found orbiting another star, a supposed world circling the pulsar PSR 1829-10. After rechecking his team's calculations, he realized the apparent planetary signal was just an artifact of improperly accounting for Earth's motion around the Sun. At a 1991 meeting of the American Astronomical Society, he walked up to the microphone, publicly retracted the discovery, and explained the mistake in front of his peers. Instead of criticism, he received thunderous applause for his honesty, and his retraction became a classic example of scientific integrity in action.
