Sagittarius A* (pronounced “Sagittarius A-star”) is the most plausible candidate for the location of the supermassive black hole at the centre of our galaxy. The black hole at the centre of the Milky Way lies at a distance of 26,000 light years from Earth. Sgr A can’t be seen in optical wavelengths because it is hidden from view by large dust clouds in the Milky Way’s spiral arms. The Galactic centre is best observed in infrared light and radio waves.
