Primordial quasar, artwork. Quasars are large galaxies with supermassive black holes at their centres. The gas and dust falling towards the black hole glows extremely brightly. This quasar, from early in the history of the universe, is surrounded by gas, dust, star clusters and stars. Observations of very distant, and so very old, quasars by the Hubble Space Telescope and the WMAP spacecraft have shown them emitting iron, indicating that stars had completed life-cycles, during which they created and released this iron, within the first few million years of the universe.
