MAXI J1820+070: Black hole outburst caught on video
The companion star orbiting the black hole has about half the mass of the sun. The black hole's strong gravity pulls material away from the companion star into an X-ray emitting disk surrounding the black hole.
While some of the hot gas in the disk will cross the "event horizon" (the point of no return) and fall into the black hole, some of it is instead blasted away from the black hole in a pair of short beams of material, or jets. These jets are pointed in opposite directions, launched from outside the event horizon along magnetic field lines.
Many things are taking place:
Cosmic Search Continues for Supermassive Black Hole Collisions
A new study led by postdoctoral researcher Xingjiang Zhu from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav), at Monash University, developed a new method to detect colliding supermassive black holes in our Universe.
In parallel, astronomers have been looking for the collision of supermassive black holes with light. A number of candidate sources have been identified by looking for regular fluctuations in the brightness of distant galaxies called “quasars.” Quasars are extremely bright, believed to be powered by the accumulation of gas clouds onto supermassive black holes.

Black holes completely break the laws of physics with their singularity at the centre, which is a one-dimensional point where gravity becomes infinite and space and time become curved.

The friction generated by these discs as they are pushed and shoved by the extreme gravitational force is so large that it can produce a tremendous amount of energy, depending on the size of the black hole.
According to astrophysicist Paul Stutter, getting close to the accretion disc would burn you to a crisp.
Why is our galaxy's black hole blinking at us?
The Moon revolves around the Earth, Earth revolves around the Sun, and the Sun — along with everything else in our galaxy — revolves around a supermassive black hole that sits at the very center. It's a dance that began long before we got here, but scientists are doing their best to make up for the lost time by explaining how black holes work, why they exist, and what they can teach us about the formation of the universe.
In a new paper published in The Astrophysical Journal Letters , researchers describe their observations of rapidly-flickering light curves coming from the location of Sgr A*. Black holes themselves don't glow or emit light, so what could it possibly be?

Lake Effect's Audrey Nowakowski speaks with astronomy contributor Jean Creighton about what astronomers know about black holes so far and how the coronavirus has impacted astronomical research.
While 1,000 light-years may seem like a vast distance away from Earth, it's practically in our backyard because of the scale of the universe. And it's just 1,000 light-years away from Earth where astronomers found the closest black hole to the Earth in the double-star system HR 6819 .
