Mysterious flashing seen near supermassive black hole. Astronomers have an idea what it is
A black hole infamous for strange features has once again baffled astronomers, this time with rapid X-ray flashes. What could they be?
A supermassive black hole is sending out a mysterious pulsing beat
Regular pulses of X-ray radiation emanating from a supermassive black hole could be explained by a white dwarf star on the verge of falling in
Strange Flashes Could Be Signs of Closest Object Seen Near a Black Hole
Black holes themselves emit no light, but the supermassive black holes at the centers of galaxies are often surrounded by huge clouds of material. It's this material, heated by friction and gravity as it swirls in orbit around the black hole, that blazes with light.
White Dwarf Is Refusing To Be Eaten By Supermassive Black Hole
According to the calculations, the likely object was a white dwarf about 10 percent the mass of the Sun. It was moving about one-third of the speed of light, completing a 100 million kilometers (61 million miles) orbit in just 18 minutes, in the early days.
Astronomers Found Strange, Accelerating X-Ray Pulses Coming From a Black Hole. They Might Be a Sign of an Orbiting White Dwarf
A supermassive black hole in a distant galaxy is once again surprising scientists. In 2018, a black hole called 1ES 1927+654, located about 270 million light-years away from Earth, showed its first signs of mysterious behavior.
X-ray flashes from a nearby supermassive black hole accelerate mysteriously
Astronomers observed flashes of X-rays coming from a supermassive black hole at a steadily increasing clip. The source could be the core of a dead star that's teetering at the black hole's edge.
