Mysterious X-ray Flashes Accelerate from Nearby Supermassive Black Hole
2025-01-14
Astronomers have observed a supermassive black hole, 1ES 1927+654, 270 million light-years away, emitting periodic X-ray flashes that have increased in frequency from once every 18 minutes to once every 7 minutes over two years. Researchers hypothesize this is due to a white dwarf star spiraling dangerously close to the black hole's event horizon. This white dwarf appears to be performing a delicate balancing act, shedding matter to prevent it from falling in. This discovery challenges our understanding of black hole environments and offers a chance to verify the theory using future gravitational wave detectors like LISA.
