1ES 1927+654 is a type 2 Seyfert galaxy located 270 million light-years away in the constellation of Draco, containing an active galactic nucleus. It is the subject of academic papers analysing its unusual characteristics. Its supermassive black hole is found massive and is a source of X-ray flashes.
