Plusieurs télescopes de l’ESO au Chili ont pour la première fois détecté la contrepartie visible d’une source d’ondes gravitationnelles. Ces observations historiques suggèrent que ce singulier objet résulte de la fusion de deux étoiles à neutrons. Les conséquences cataclysmiques de ce type de fusion – des événements prédits de longue date et baptisés kilonovae – disséminent des éléments lourds tels que l’or et le platine dans tout l’Univers. Cette découverte a fait l’objet d’une série d’articles publiés au sein de revues telle Nature. Elle apporte la preuve irréfutable que les sursauts gamma de courte durée sont causés par les fusions d’étoiles à neutrons.
