Biography
Michel Gustave Édouard Mayor was born on January 12, 1942, in Lausanne, Switzerland. He studied at the University of Geneva and the University of Lausanne, gaining a strong background in astrophysics that shaped his career. Mayor spent much of his career at the University of Geneva's Department of Astronomy, where he became a professor and conducted pioneering work in stellar astronomy and planetary detection. Although he officially retired in 2007, he continues his research at the Observatory of Geneva as a professor emeritus.
Mayor's most important contribution to science happened in 1995 when he and his doctoral student Didier Queloz discovered 51 Pegasi b, the first confirmed exoplanet orbiting a sun-like star. This discovery changed astronomy by proving that planets exist beyond our solar system around stars like our Sun. The planet, about 50 light-years from Earth, was found using the radial velocity method, which measures the slight wobble of a star caused by the gravitational pull of a planet.
The 1995 discovery launched a whole new area of astronomical research and sparked a lot of interest in exoplanet detection. Mayor's work showed that planetary systems are common in the universe, leading to thousands of exoplanet discoveries. His research methods and techniques became key tools for astronomers worldwide trying to find and study planets orbiting other stars.
Mayor's scientific achievements have been acknowledged with many prestigious awards throughout his career. He received the Nobel Prize in Physics in 2019, sharing it with Jim Peebles and Didier Queloz for their contributions to understanding the universe and Earth's place in it. Other major honors include the Wolf Prize in Physics (2017), Kyoto Prize in Basic Sciences (2015), Gold Medal of the Royal Astronomical Society (2015), Balzan Prize (2000), and Knight of the Legion of Honour (2004). Despite the impacts of exoplanet discoveries, Mayor remains realistic about space exploration, pointing out that the huge distances involved make human migration to these worlds impossible with current technology.
Before Fame
Mayor's early career grew during a time when significant advancements were happening in astronomy. The mid-20th century saw better telescopic precision and computer processing power, essential for spotting the tiny star movements caused by orbiting planets. He studied at Swiss universities, gaining a strong background in math and stellar physics.
Finding exoplanets needed decades of technological and theoretical work. Before Mayor's breakthrough, astronomers had long wondered about planets around other stars but didn't have sensitive enough instruments to find them. Mayor spent years improving radial velocity measurement techniques, achieving the precision needed to detect the small star wobbles that would indicate planetary companions.
Key Achievements
- Co-discovered 51 Pegasi b in 1995, the first confirmed exoplanet orbiting a sun-like star
- Won the 2019 Nobel Prize in Physics with Jim Peebles and Didier Queloz
- Pioneered radial velocity techniques that became standard methods for exoplanet detection
- Opened the entire field of exoplanet astronomy through his groundbreaking research
- Received multiple prestigious scientific awards including the Wolf Prize and Kyoto Prize
Did You Know?
- 01.The planet 51 Pegasi b that Mayor discovered orbits its star in just 4.2 days, making it a 'hot Jupiter' - a gas giant much closer to its star than any planet in our solar system
- 02.Mayor initially thought the data showing 51 Pegasi b might be an error because the planet's properties were so different from anything in our solar system
- 03.He has stated that humans will never travel to exoplanets because they would require 'hundreds of millions of days' to reach using current technology
- 04.Mayor's discovery was made using the ELODIE spectrograph at the Haute-Provence Observatory in France
- 05.The Nobel Prize he shared was announced exactly 24 years after his groundbreaking exoplanet discovery
