Illustration showing a quasar (orange) surrounded by a gas halo (blue) in the early universe. The quasar has two powerful jets and a supermassive black hole at its centre, which is surrounded by a dusty disc. Astronomers studying quasars as they were in the early universe have discovered some had large gas reservoirs, needed to grow supermassive black holes. | |
