The Full Story
In 1995, astronomers Michel Mayor and Didier Queloz announced the discovery of 51 Pegasi b, the first confirmed exoplanet orbiting a Sun-like star. It was found using the radial velocity method, which detects tiny wobbles in a star caused by a planet’s gravity. The discovery transformed astronomy because it proved planets were common beyond the Solar System. Mayor and Queloz later received the 2019 Nobel Prize in Physics for this work.
