This Supermassive Black Hole May Harbor a Bizarre Star That Refuses to Die
Strange x-ray pulses hint at a surprisingly long-lived white dwarf orbiting precariously close to a supermassive black hole
Feeding supermassive black holes may have ended the cosmic 'dark ages' billions of years ago
"Finding more supermassive black holes that are potentially hosting jets raises the question as to how these black holes grew so big in such a short timescale."
Astronomers capture unprecedented view of supermassive black hole in action
Active galactic nuclei are supermassive black holes at the center of certain galaxies. As matter falls into these black holes, enormous amounts of energy are released, making active galactic nuclei, or AGN,
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?
Feeding supermassive black holes are more common than thought across the universe
"If our eyes were able to detect X-rays, the sky would be full of dots. And every single one of those dots would be an accreting supermassive black hole."
A strange black hole is acting even stranger
A strange black hole is making scientists scratch their heads.
Astronomers Discover ‘Swarm’ of Black Holes Whipping Around the Milky Way Galaxy
Black holes are some of the universe's greatest mysteries, incredibly dense and sometimes massive void that suck in anything and everything that passes their event horizons. Now a relatively nearby star cluster known as Palomar 5,
Scientists have just realised the universe has more supermassive black holes than anyone believed
According to scientists, there could be more black holes in the universe than previously thought. Researchers reckon astronomers could be missing between 30 per cent and 50 per cent of the feeding supermassive black holes,
Revolutionary Telescope Captures Sharpest View Ever of a Supermassive Black Hole in Action
Astronomers have captured the most detailed infrared images yet of an active galactic nucleus (AGN), using the Large Binocular Telescope Interferometer. This breakthrough enables unprecedented insight into the energetic phenomena surrounding supermassive black holes at the centers of galaxies,
Astronomers observe real-time formation of black hole jets for the first time
In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to dramatically increase its output again in 2023. At that time,

'It was very fortunate timing': Astronomers watch 1st black hole to 'shut off' blast back to life
The first black hole that astronomers observed "turning off" just turned back on, releasing jets of hot gas into the cosmos.
