Astronomers find hundreds of 'hidden' black holes — and there may be billions or even trillions more
Black holes that have been obscured by clouds of dust still emit infrared light, enabling astronomers to spot them for the very first time.
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 Pulsing X-Rays From a Nearby Black Hole Baffle Astronomers
MIT astronomers have been captivated by the strange behaviors of a supermassive black located 270 million light-years away, which mysteriously lost and then regained its corona in 2018. Recently, it e
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."
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?
'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.
Astronomers capture the highest resolution images ever taken of a black hole
Active galactic nuclei (AGN) are among the most energetic phenomena observed in the universe. These luminous objects, powered by supermassive black holes at the centers of galaxies, release staggering amounts of energy as matter spirals into their intense gravitational pull.
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,
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,
Astronomers Discover Supermassive Black Hole Firing a Powerful Energy Beam at Earth
Astronomers have identified a rare cosmic phenomenon: a supermassive black hole, known as J0410−0139, located 12.9 billion light-years from Earth. This black hole, with a mass equivalent to 700 million suns,
