Quasar J0529-4351:
Consuming just over one Sun's worth of matter each and every day, it is the fastest growing black hole detected so far. Also, the intense amount of energy it emits in the process of eating all that matter makes it the brightest quasar ever seen.
And since quasars are already the brightest objects in the universe, this is also the most luminous known object in the universe. It's 500 trillion times brighter than our Sun and 17 billion times its mass.
Located 12 billion light year away.
