Constelation of Sagitarius, distant from 19,000 light years. ESO discovered a microlensing by a black hole with a mass twice of the Sun. Maybe it lies inside the cluster. It brings out an amplified image of red giant star of the background of the object .

I didn't understand who the ESO's arrow is pointing exactly: the stars near its tip or the red star near and on its direction.
