Le noyau interne de la Terre est un véritable mystère - voici comment les scientifiques commencent à le résoudre
Sous nos pieds, à une profondeur stupéfiante de plus de 5 100 km, se trouve le noyau interne de la Terre, une solide boule de fer et de nickel qui joue un rôle crucial dans la formation des conditions que nous connaissons à la surface. En fait, sans lui, il est peu probable que nous puissions exister.
