The video discusses Sagittarius A, the supermassive black hole at the center of the Milky Way, and its influence on six strange objects, G1 to G6, that orbit it. These objects have elongated orbits ranging from 100 to 1000 years. The black hole's gravity stretches these objects, stripping away their outer gas shells. Observations of G2 reveal that despite this stretching, it retains a coherent dust core, suggesting a stellar object inside. It is speculated that these G objects were once binary stars that merged due to the black hole's gravitational influence.
