DIDIER QUELOZ Meaning and
Definition
-
Didier Queloz is a French-Swiss astronomer who is renowned for his contributions to the study of exoplanets, particularly his discovery of the first confirmed exoplanet orbiting a Sun-like star. Born on February 23, 1966, Queloz obtained a degree in physics and completed his doctoral studies in astrophysics at the University of Geneva.
With his colleague, Michel Mayor, Queloz made a groundbreaking discovery in 1995 of a massive planet named 51 Pegasi b, located approximately 50 light-years away from Earth. This exoplanet orbits its host star in only 4.2 days, defying the previously held belief that large planets can only exist in wide orbits around stars. This discovery revolutionized the field of astronomy, leading to a surge in exoplanet research.
Queloz's work has had a significant impact on our understanding of the universe, demonstrating that other planetary systems exist beyond our Solar System. His research has provided valuable insights into the formation and evolution of exoplanets, offering clues about the potential for habitable worlds elsewhere in the galaxy.
In recognition of his pioneering contributions, Queloz was awarded the Nobel Prize in Physics in 2019, jointly shared with Michel Mayor. This prestigious accolade solidified his status as one of the most prominent figures in the field of exoplanet research and showcased the importance of his discoveries in expanding our knowledge of the cosmos.
