GENEVA - For Michel Mayor of the University of Geneva Observatory, it was an impressive list of achievements: his team managed to discover no less than 50 new exoplanets orbiting around another star than our sun, thanks to the HARPS spectrometer located at La Silla Observatory in Chile.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.
