There's a hurricane surrounding a supermassive black hole 75 million light-years away and astronomers have clocked its speed to calculate the black hole's mass: a whopping 660 million times the mass of our sun.
A highly sensitive radio telescope has seen something peculiar in the depths of our cosmos: A group of supermassive black holes are mysteriously aligned, as if captured in a synchronized dance.
The true nature of mysterious fast radio bursts (FRBs) may not have been revealed after all.
Astronomers have found a monster black hole, some 17 billion times more massive than the sun, in a modestly sized galaxy, raising suspicions that supermassive black holes may be much more common than originally thought.
New measurements show that quasars can blow far past the theoretical temperature limit of 100 billion degrees Kelvin (179 billion degrees Fahrenheit), which has scientists puzzled.
Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests.
Astronomers have observed a supermassive black hole in a distant quasar and made a stunning discovery -- it's spinning one-third the speed of light.
The pair of black holes the set off the first detection of gravitational waves through space may have been spawned by the death of a single, massive star.
