Answer: Active Galactic Nucleus
Notes: Astronomers announced the discovery of J0529-4351, the brightest and fastest-growing quasar to date. This quasar harbors a supermassive black hole 17 billion times the Sun's mass. Quasars are active galactic nuclei (AGNs), fueled by supermassive black holes at a galaxy's center. Not all AGNs are quasars, which form in regions of high matter density. Quasars are exceptionally luminous and powerful cosmic phenomena, arising from active galaxies with intense matter consumption, leading to the formation of spiraling accretion disks.
