(IMAGE) University of Cologne Caption The Galactic centre at a distance of about 30000 light years. In the centre of the image is the supermassive black hole Sgr A* (not visible). The position of Sgr A* can be inferred from the motion of the stars. Because of the dust cloud and its dimensions around X3a the baby star is also not visible in this image.
