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
There might be far more supermassive black holes hiding around us than we thought, scientists warn
The universe could be home to far more supermassive black holes than we realised, according to new research. Astronomers from the University of Southampton say that 35% of these galactic giants - some which are billions of times heavier than the sun - have gone undiscovered because they are obscured by thick clouds of gas and dust.
First-ever detection of a mid-infrared flare in Sagittarius A*, the Milky Way's supermassive massive black hole
Using the MIRI instrument onboard the James Webb Space Telescope, an international team of scientists made the first-ever detection of a mid-IR flare from Sagittarius A*, the supermassive massive black hole at the heart of the Milky Way.
About a third of supermassive black holes are hiding
Supermassive black holes can have trillions of times more mass than the Sun, only exist in specific locations, and could number in the trillions. How can objects like that be hiding? They’re shielded from our view by thick columns of gas and dust.
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?
Mysterious x-ray flashes are accelerating in a black hole
Astronomers detected X-ray flashes from the black hole that increased in frequency from one every 18 minutes to one every seven minutes.
Astronomers detect rare X-ray flares from black hole 1ES 1927+654 caused by a nearby white dwarf
The observations revealed features never before seen in real time around a supermassive black hole. Among them was the launch of a plasma jet moving at nearly one-third the speed of light.
