by Quasars are thought to result from supermassive black holes gobbling up surrounding matter, such as gas or even entire stars, resulting in a maelstrom of superheated matter known as an accretion disk that swirls around the black hole.
Because of the enormous energies involved, quasars are among the brightest sources in the Universe, often outshining their host galaxies.
Although J0313-1806 is only 20 million light-years farther away than the previous record holder, ULAS J134208.10+092838.61, it contains a supermassive black hole twice as heavy. This marks a significant advancement for cosmology, as it provides the strongest constraint yet on the formation of black holes in the early Universe.
