Observatory of Geneva
Genève
Located in Sauverny near Geneva, Switzerland, the Geneva Observatory is a prominent astronomical research institution affiliated with the École Polytechnique Fédérale de Lausanne. It has played a pivotal role in modern astronomy, notably through the discovery of the first exoplanet orbiting a main-sequence star, 51 Pegasi b, by Michel Mayor and Didier Queloz in 1995, a breakthrough that earned them the Nobel Prize in Physics in 2019. The observatory operates several telescopes, including a 1-metre telescope at Haute-Provence Observatory in France, the 1.2-metre Leonhard Euler Telescope, and the TRAPPIST telescope in Chile, specializing in exoplanet and comet observation. It actively participates in major space missions such as ESA's Hipparcos, INTEGRAL, Gaia, and Planck. Historically, the Geneva Observatory was instrumental in certifying the precision of mechanical timepieces, contributing to the advancement of horology. Its research encompasses stellar photometry and evolution modeling, making it a hub for cutting-edge astronomical science. The observatory's international collaborations and technological contributions underscore its significance in both scientific and cultural contexts.

Histoire
The Geneva Observatory was founded to advance astronomical research and played a key role in precision timekeeping by testing mechanical watch movements for accuracy, issuing the prestigious Bulletin de Marche certificates.
This role was crucial in driving improvements in mechanical watch precision until quartz technology redefined time measurement in the mid-20th century.
The observatory's involvement in exoplanet discovery marked a new era in astronomy, highlighted by the Nobel Prize-winning detection of 51 Pegasi b in 1995.
Over time, it expanded its facilities and international collaborations, contributing to major space missions and ground-based telescopic surveys.
