The Paris Observatory salutes the Nobel Physics Prize awarded to Michel Mayor and Didier Queloz for their discovery in 1995 of the first exoplanet.

Michel Mayor and Didier Queloz have made an outstanding contribution to a new view of the Universe via their discovery of an extrasolar planet, I.e. a planet orbitting a star other than the Sun.

This exceptional result was due to various observational improvement made by them and, including the development of a new generation of spectrographs.

They have also developed a method know as the «radial velocity method», which uses spectrographs to measure exoplanet speeds.

In recognition of the excellence of this work and the special relation established with the Paris Observatory, Michel Mayor had already received on October 23rd 2008 the title of Docteur honoris causa of the Paris Observatory.
