A Story Of Black Holes: Sagittarius A*. Identifying our galaxy’s supermassive black hole by tracking stars’ orbits. A black hole is a region of space packed with so much mass that its own gravity prevents anything from escaping—even a ray of light.
Zooming into the black hole (Sgr A*) at the centre of our galaxy. Beginning with a broad view of the Milky Way, we dive into the dense clouds of gas and dust at our galactic centre. The stars...
