TON 618
TON 618, the largest known black hole in the universe, had always been a bit of a loner. Sure, he had his fair share of admirers and curious onlookers, but none of them could truly understand the depths of his darkness or the power he wielded. That is, until he met S5 0014+81, a smaller black hole with a mischievous sense of humor.
