This infrared image from the NASA/ESA Hubble Space Telescope shows the centre of the Milky Way, 27 000 light-years away from Earth. Using the infrared capabilities of Hubble, astronomers were able to peer through the dust which normally obscures the view of this interesting region. At the centre of this nuclear star cluster and also in the centre of this image the Milky Ways supermassive black hole is located.
