Two large, unknown objects have been observed emerging from the brightest black hole in the universe.
Supermassive black hole 3C 273 is a quasar, short for "quasi-stellar object," since its light is brilliant enough to be mistaken for starlight.
The largest black holes are surrounded by accretion discs that emit radio waves when gas falls into them at almost the speed of light.
3C 273, the first quasar. It's 4 trillion times brighter than Earth's sun 2.4 billion light-years away.
Radio emissions from a quasar revealed two massive radio structures. Quasar 3C 273 was seen by Hubble and ALMA telescope . The dim radio item is blue-white and the bright energy jet is orange.
One structure is a radio light smudge tens of thousands of light-years to the southwest. This radio fog overlaps with a long astrophysical jet.
Depending on the radio frequency, jet emissions can appear brighter or dimmer, but galaxy 3C 273's vast radio structure was spectacular.
Radio fog around the galaxy is star-forming hydrogen gas ionised by quasars. Even though the quasar ionised a huge amount of gas, star formation remained unaffected.
