An article published in the journal “Nature” reports the identification of what were called G-objects that orbit the supermassive black hole at the center of the Milky Way, Sagittarius A* or simply Sgr A*. A team of researchers led by Anna Ciurlo of UCLA already announced the discovery of three new G-objects, now they confirm their existence and announce the identification of a fourth one. They add to the two G-objects already confirmed a few years ago. New indications could confirm the hypothesis that they’re the result of mergers of binary systems’ stars.
