[00:00:00]Did you know that galaxies can have quasar light echoes that are billions of years old? These echoes are essentially reflections of intensely bright light that was emitted by a quasar, a massive and incredibly luminous object at the center of the galaxy. The quasar is powered by a supermassive black hole that is actively accreting material, releasing enormous amounts of energy in the process.
