Near the earth!Two galaxies touched each other, and the two huge black holes merged!

This pair of black hole combinations that are underway are the closest to the earth we have found

Scientists have predicted that a pair of black holes that are difficult to capture may be hidden in a nearby galaxy. Now they can finally see this pair of black holes.

A pair of extra -large quality black holes that are about to be combined into one have been found in a nearby galaxy.

These two black holes are danced around each other. They are located in the center of the Aquarius constellation and the 89 million light -year -olds of the earth.

Scientists said they have never seen such a combination: they are so close to our planets and so close to each other.

The reason why this black hole combination, which was combined in one of 250 million years later, was a long time beyond the detection. It was inexplicably not radiating many X -ray radiation -usually this factor pointed to the existence of black holes. This pair of black holes was discovered and analyzed by a strong pair of towering telescopes: huge telescope and Hubble space telescope in the southern Okinet (ESO) in Chile.

The first black hole picture extends the polarization update, and the more secrets of the magnetic field will be revealed.

"This is the first time we have discovered two so close -up black holes that are so close to. The distance between them is less than half of the previous record holders," Karina Fogel said in the statement. A astronomer and chief writer of the new research project in Strasbourg, France.

The previously closest black hole combination record holder is 470 million light years from the earth, which is five times the latest black hole combination. The similarity of the black hole combination in the NGC7727 allows astronomers to be able to confirm their quality by measuring how nearby stars are affected by their gravity.

The larger one of the two black holes is about 154 million sun. The quality of the smaller one is the 6.3 million times that of our stars, which surrounds its partners on the orbit that is only 1,600 light years.

Extra -quality black holes are usually located in the center of the huge galaxy, and when the two galaxies collide and integrate, the black holes will be the case.

Scientists said that the discovery provides information about large -scale black holes, but it also means that there may be more black holes and combined combinations lurking in nearby galaxies.

"Our discovery implies that there may be a lot of such galaxies in space, and they may have a lot of huge black holes to be discovered," Ferger said. "This may be The number of large quality black holes in the universe increases by 30 %. "

Scientists are expected to search for large -quality black holes and black holes in the next few years, thanks to the prediction of the Great Telescope (ELT) of Beixi ESO, which will be completed in 2024.

"With the assistance of Harmoni's (high -angle resolution single -chip optics and near -infrared light integrated viewfield spectrometers), we will be able to complete a deeper detection than now," · Misk said in a statement that he was a co -writer of the study.

Black Hole (English: Black Hole) is an area that shows extremely powerful gravity in time and space, so that all particles and even electromagnetic radiation cannot escape [6]. The general theory of relativity predicts that the tight quality can distort time and space to form a black hole [7] [8]; the boundary that cannot escape from the area is called event vision (English: Event Horizon). Although the event field has a huge impact on the fate and situation of the objects that cross it, the observations of the region seem to fail to detect any features [9]. In many ways, the black hole is like an ideal black body, it does not reflect [10] [11]. In addition, the quantum field theory in the bending time and space predicts that Hawking radiation emitted by the incident vision can be used to measure the temperature of the inverse proportion of quality as the black body spectrum. In the black hole of the star quality, this temperature is often one billionth K, so it is basically impossible to observe.

As early as the 18th century, John Michelle and Pie Simon Laplas considered objects that could not escape from light to light. [12].In 1916, Karl Starcas discovered the first exact relativity accurate solution to represent the black hole (that is, Sawasis black hole).As an interpretation of an unable to escape the space area.For a long time, Black Hole has been considered to be only curious in mathematics.In the 1960s, theoretical work showed that this was a general prediction of general relativity.Joseine Bell Bernes discovered neutron stars in 1967, inspiring the density celestial body formed by people's gravitational collapse may be the entity in celestial physics.By: Tereza Pultarova
