Who is Didier Queloz?
Didier Queloz is a Swiss astronomer and professor, recognized worldwide for his groundbreaking discovery of the first exoplanet orbiting a Sun-like star. His career is a clear example of perseverance and of how scientific curiosity can transform our understanding of the universe. With a rigorous work ethic and a bold vision, Queloz has established himself as one of the most influential figures in modern astronomy. His discovery not only ushered in a new era of science and exploration but also forced us to reevaluate our place in the cosmos—a paradigm shift that was celebrated worldwide.
In 1995, while working on his doctoral thesis at the University of Geneva, Queloz and his thesis advisor, Michel Mayor, observed a slight wobble in the star 51 Pegasi. This wobble suggested the presence of an invisible planet. After months of rigorous analysis and in-depth research, they confirmed the discovery, which would become the first exoplanet ever discovered. This planet, named 51 Pegasi b, was a “hot Jupiter” and challenged the astronomical theories of the time, which held that such planets could not exist so close to their stars, opening the door to a new field of research.
Queloz and Mayor’s discovery was a historic milestone. It paved the way for the search for thousands of exoplanets, revolutionizing astronomy and astrophysics. This work laid the groundwork for the development of new technologies and space missions dedicated to detecting planets in other galaxies, including the Kepler Space Telescope and TESS. For their invaluable contribution, Queloz and Mayor were awarded the Nobel Prize in Physics in 2019, a well-deserved recognition of work that changed the paradigm of science and the way we search for life beyond Earth.
Following this discovery, Didier Queloz has devoted himself to teaching and research at the University of Cambridge, where he continues to explore the mysteries of the universe. His legacy is marked by his ability to inspire a new generation of astronomers and by his valuable contribution to the debate on the possibility of life on other planets.
