Astronomers have just discovered a galaxy with a supermassive black hole at its core, and it’s located over 12.8 billion light-years away from Earth, just a billion years shy of the Big Bang. Known as a quasar, this object is the brightest of its kind ever seen in the distant universe. The discovery gives scientists a better look at the universe’s early years and helps them understand how supermassive black holes form and evolve.

The newfound quasar, dubbed UHS J043947.08+163415.7, was discovered by taking advantage of gravitational lensing, a phenomenon in which a distant object’s light is magnified by the gravity of a closer object. The intervening, or lensing, galaxy in this case makes the quasar appear 50 times brighter than it would otherwise. [Big Bang to Civilization: 10 Amazing Origin Events]
