By Pierre Léna, astrophysicist and Professor Emeritus, Observatoire de Paris – PSL & Université Paris Cité, member of the Académie des sciences
In 1973 over Africa, the Concorde-001 prototype, piloted by André Turcat and flying at Mach 2 in the shadow of the Moon, offered the nine scientists on board the longest totality of a solar eclipse: 74 minutes. Fifty years on, the solar corona, more easily observed from space and responsible for a new meteorology, still raises questions. The Lyot Coronagraph, born at Pic-du-Midi to study this corona, now installed on the JWST telescope, discovered a remarkable exoplanet, while its successor will be looking for Earth’s twin sisters.
Following the conference, Pierre Léna will be available for book signings. The Librairie de la Renaissance will also be on hand at the entrance to sell its books.
Free admission in the limit of available seats.
