It absorbs a black hole from a star to absorb the material, with a telescope mounted at the International Space Station

The high-resolution X-ray telescope mounted at the International Space Station made an incredible measurement of black holes in black science so that astronomers could have an important impact on understanding these mysterious objects.

Scientists know that black holes emit energy X-rays that emit material, but how and where the debate has been. The Neutron Star Interior Composition Explore or NICER gave scientists the chance to observe X-rays ever before; Because it helped to better understand the black holes in the black masses of periodic mass of the Sun, but also the giant center that multiplies a thousand million solar masses.

"It's been discussed how black holes evolve," said Erin Kara, University of Maryland and the Goddard Space Flight Center at NASA, Gizmodo. "We see when they fall apart when inappropriate things fall apart … The origin of the explosion is something that was debated from the discovery of black holes."

The black holes are space regions, so massive and compact, which is called a horizon of events, which can be escalated into matter or energy (including visible light) can be escaped from the gravitational attraction. But when they absorb it from a friend of matter, they show a complex structure. The "acceleration disk" of the black hole gravity like Saturn's rings, and the hot gas called the crown is placed in the black hole pole. These excessive absorption events are usually accompanied by X-ray high-energy X-rays explosions. They are converted into X-ray energy generated on the increase disk.

But how does this absorption process progress? Does the disk start faster and then you approach the event horizons? Or is the crown moving out of the black hole next to the disc?

To understand this process, high-resolution X-ray measurements are required. Scientists call reverberations or "echo lights". Light echoes are essentially X-rays with crowns, largely the effect of the acre disk, which generates little X-ray energy. They are interested in measuring the initial flash and the energy echo.

The scientists saw the echo of the light black hole called MAXI J1820 + 070 with NICER. The data reveals that the delay is six to 20 times shorter than the previous measure, according to research published in Nature magazine. This NICER can measure more time than other tools.

"Measuring the range of light expectations to measure the row margin, is half a millisecond," Kara said. In this way, scientists could measure X-rays and their echoes around 300 nanosecond resolution around a black hole around 10,000 light years.

The researchers turned into an inference about the process of collecting this measure. There was a shorter echo when it was closer to the horizon, before it was thought, it means that the crown becomes smaller and the accretion disk is not approaching.

"We have seen a lot of tensions that we saw in the measures that we saw in order to solve the measures," said an assistant professor of physics at Daryl Haggard McGill University.

But the analysis has limits. Haggard warns that this is the source. "The black hole could be a certain behavior of the noise system," he said. "This is always a problem if you have only one source, we want to see the same behavior that is seen in the explosions of other massive black masses." And also interpretations that are consistent with other data.

However, the analysis may have important consequences. It would solve the instability between big supermassive black holes and smaller stellar black holes. Black holes supermassive discs extend almost completely to the black hole, and the previous measurements did not indicate discs of small black holes, mixed discourse. New results show maybe a better team.

Observation is important and there is more than just a small black hole in the form of black holes. And it is good that we have learned in a telescope mounted at the International Space Station.
