New study looks at how to harness energy from a black hole
... Physical Review, two researchers are suggesting that by breaking and rejoining magnetic field lines near the event horizon, a source of power could in the future be extracted to support the needs of an advanced civilisation. Mining energy from black...

For the first time, astronomers image magnetic fields around M87 black hole
... it resist gravity’s pull. Only the gas that slips through the field can spiral inwards to the event horizon,” explains Jason Dexter, Assistant Professor at the University of Colorado Boulder, US, and Coordinator of the EHT Theory Working...

Ring of fire around black hole revealed for first time
.... Last year ESO’s GRAVITY instrument observed a ring of extremely fast moving material racing around near Sag A*’s event horizon at about 30 percent the speed of light. As tantalising as the observation was, the massive cavernous abyss of the black...

Black hole 'bath' confirms wave phenomena
Using water and a generator to create waves, astronomers have been able to gain valuable insights into how a particular phenomena known as superradiance affects particles around a black hole. Rotational superradiance is a technical term for how ...

Gravitational waves proved Einstein right, now they may help prove him wrong too
..., escapes as it is sucked into the beckoning void has been turned on its head in recent decades. Theories from event horizon ‘fuzzballs’ to ‘firewalls’ have been suggested to overcome the lost information problem associated with our classical view...

Black hole status of the Milky Way centre confirmed with striking new data
... ESO’s GRAVITY instrument, a ring of extremely fast moving material has been spotted racing around near its event horizon at about 30 percent the speed of light; this is the most detailed observations yet of material swirling around so close...
