The supermassive black hole Sagittarius A* is seen towards the centre of the photo of our Milky Way galaxy’s galactic core. Taken with NASA’s Chandra X-ray observatory satellite the photo reveals a neighbourhood of young massive stars near this black hole. The image is a composite of both X-ray and infrared light, and helps in understanding how stars are produced in galaxies.
