Du strontium a pour la toute première fois été détecté dans l’espace. La création de cet élément lourd fait suite à la fusion de deux étoiles à neutrons. Cette découverte a été effectuée par le spectrographe X-shooter qui équipe le Very Large Telescope de l’ESO. Elle fait l’objet d’une publication ce jour au sein de la revue Nature. Cette détection confirme la possibilité que les éléments les plus lourds de l’Univers se forment lors de la fusion d’étoiles à neutrons, complétant ainsi le puzzle de la formation des éléments chimiques.
