Scientists observe unusual X-ray flashes from supermassive black hole, hinting at nearby white dwarf.

Scientists have observed a supermassive black hole, 1ES 1927+654, showing unusual behavior including X-ray flashes that have increased in frequency from every 18 minutes to every 7 minutes over two years. This activity could be due to a white dwarf orbiting the black hole, marking the closest known object to a black hole's event horizon. The discovery may lead to detecting gravitational waves with future observatories like NASA's LISA.
