There are black holes. The first one was found in the late 20th century and it was confirmed. Astronomers find them everywhere. There are two black holes in the center of our universe, one in M87 and the other in Sagittarius A*.
We don't know much about them. A large amount. There is more to be found.
Astronomers using Chandra X-ray Observatory data have discovered a super massive black hole in a quasar embedded in a distant galaxy cluster. Clues to the origin and evolution of black holes are provided by what they found.
There are many challenges to studying a black hole. Every large galaxy has a black hole. We need to know as much as we can about them. Billions of solar mass can be found in these giant giants.
Nothing can escape their clutches. That makes it harder for us to see them and their regions.
It's not clear how these monsters form and evolve.
They have two of their characteristics. Julia Sisk-Reynes of the Institute of Astronomy (IoA) at the University of Cambridge said that black holes can be defined by their spin and mass.
It's not easy to figure out the values for most black holes.
There are ways to measure the mass. Data from the Chandra X-ray Observatory was used to learn more about black holes.
The black hole engine of the quasar may have a spin rate. The mass of the Sun is 30 billion. The central black hole in the Milky Way has only about 4 million suns.
What is the reason for X-rays? A spinning black hole allows matter to travel closer to it than a non-spinning one. The black hole spins quickly.
The black hole rotation rate of H1821+643 is weird, compared to other less massive black holes that spin at close to the speed of light. The team was surprised by the slower rate.
Christopher Reynolds is an astronomer at the Institute of Astronomy and he said that the black hole in H1821+643 is spinning less than most black holes. He is one of the authors of the paper. Why is the million dollar question?
James Matthews said that the history of H1821+643 could be the key to understanding its slower spin rate.
He suggests that mergers with other black holes may have been the cause of the H1821+643 black hole.
It's well known that the same activities that build up larger galaxies are also the same activities that build smaller ones.

The black hole's spin rate would be affected by these activities. Black holes can show a range of spin rates.
The violent, chaotic history of the universe's biggest black holes may be the reason for the moderate spin for this object.
It could give insight into what will happen to our black hole billions of years in the future when the universe collides with other planets.
