摘要：
Supermassive black hole binaries may exist in the centers of active galactic nuclei like radio galaxies. We imaged the radio galaxy 3C 66B at radio frequencies using the Very Long Baseline Interferometer and found that the unresolved radio core of 3C 66B shows well-defined elliptical motions with a period of 1.05 +/- 0.03 years. This result strongly suggests the orbital motion of a supermassive black hole binary.
