Conférence " Comètes, les archives du système solaire " par Karl ANTIER géophysicien et médiateur scientifique

Lecture by Karl ANTIER, geophysicist and scientific mediator, Chairman of the Meteors, Meteorites and Impactism Commission of the Société Astronomique de France.

Discovered in January by a team of French amateur astronomers, comet C/2026 A1 (MAPS) will graze the surface of the Sun on April 4, just three days after this conference.
