La collaboration Event Horizon Telescope (EHT) vient de dévoiler une nouvelle image de l’anneau de plasma entourant Sgr A*, cette fois-ci avec des données de polarisation, révélant la direction des puissants champs magnétiques qui s'enroulent en spirale autour du trou noir supermassif. Ils publient deux articles dans The Astrophysical Journal Letters.
