RadioAstron Captures Radio Image of Two Supermassive Black Holes Circling Each Other
This RadioAstron map two supermassive black holes at the center of OJ 287, a galaxy located about 5 billion light-years away in the constellation of Cancer: if the central component corresponds to the primary black hole, then the next one upwards marks the secondary black hole, and the highest component represents a knot in its jet; the elongation of the individual components is not real, but is a reflection of the beam shape.

Using data from the RadioAstron satellite, astronomers have produced a radio image of two supermassive black holes at the center of the distant quasar OJ287, where the secondary black hole is in a 12-year orbit around the primary.
