All about The Galactic Centre
The centre of our galaxy, the Milky Way, has a supermassive black hole called Sagittarius A*. Stars orbit around this centre, which lies about 26,000 light-years from Earth. The centre is hidden from view by dust, so astronomers use infrared light to see it.
Some stars near the galactic centre orbit very fast, and astronomers have tracked them for decades. Their movement helped confirm that the black hole is incredibly massive.
