Double Supermassive Black Hole is Most Compact Ever Found

Astronomers have discovered what may be the most compact binary supermassive black hole ever known in a galaxy about 400 million light years from Earth.

The binary supermassive black hole is located inside the gas-rich interacting spiral galaxy NGC 7674 (Markarian 533) in the constellation Pegasus.

The apparent separation of the two supermassive black holes in this system is less than one light-year.

That’s d*** close. Does anyone have a suggested mechanism for how such a close binary supermassive black hole can form?
