The radio signals hint at an important evolutionary step in the lives of galaxies.
A black hole is a location in space that possesses so much gravity, nothing can escape its pull, even light. Learn more about what black holes are and the latest news.
New research has found the jet blasting outward from this black hole swings like a pendulum on an 11-year cycle.
Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity.
Supermassive black holes are even more fearsome eaters than scientists suspected, thanks to a "delivery system" that could help them feed over months rather than hundreds of years.
A study of the Squid Galaxy, Messier 77, has revealed how chemicals swirl around its central black hole, revealing supermassive black holes impact the chemical evolution of their galaxies.
Astronomers normally observe galaxies by observing light these objects emit, but some tricky galaxies require a different approach.
A "Luminous Fast Cooler" explosion that emits as much energy in weeks as the sun will over 10 billion years could be the result of a black hole wrecking a star.
The frequency at which a star is being shredded by a black hole in a nearby galaxy offers clues into the poorly understood field of partial tidal disruption events.
Gravitationally lensed light from a distant quasar, powered by a supermassive black hole, could help constrain the properties of dark matter.
Einstein's theory of relativity say black holes are 'bald', but a new tweak to his research may give the mysterious objects their long-sought 'hair.'
Years after ripping stars to shreds, 24 black holes suddenly flared up with radio waves in inexplicable 'burping' bouts. Half of all star-killing black holes may experience the same.
Astronomers have imaged the outskirts of an accretion disk gradually feeding a supermassive black hole for the first time, potentially boosting our understanding of such hungry cosmic monsters.
The 'wobble' of jets blasting out from active galaxies, or blazars, is 'smoking gun' evidence for supermassive black hole binary systems that elude astronomers, a new study reports.
When supermassive black holes barrel toward collision, they can reach speeds of up to 1/10th the speed of light, new research suggests.
The way in which supermassive black holes grew to tremendous sizes in the early universe has been a mystery for astronomers, but the puzzle could soon be solved.
Reference Finding supermassive black holes with masses billions of times greater than the sun under a billion years after the Big Bang has scientists confused how these cosmic titans got so big so quickly.
Knowing that black holes tend to have these masses could help provide a new way of measuring the expansion rate of the universe.
