Scientists have found, for the first time, a black hole without other objects nearby. The Existence of these child of ‘solo flights’ or Black Holes was Already Assumed, But Now One has actual leg Seen.
Black holes are, in principle, invisible because not even light can escape their gravity. Therefore, they are almost always only seen while they are gobbling up stars or other matter. But the Newly Found Black Hole Doesn’tn’t Have Any Other Object Near It and Is Therefore Not Visible.
Scientists were still able to find it, thanks to the light from galaxies that are (seen from earth) Behind the Black Hole. That light was distorted by the huge gravity of the black hole, in a process called gravitational microlensing. The Black Hole is, in this case, a child of lens that concentrates the light to another point.
By studying the light from the galaxies, the astronomers were able to discover that the black hole is almost five thousand light-years away and more than seven times as heavy as our sun.
The Scientists published Their Results in The Journal The Astrophysical Journal . They write that their years of research show that there were no large objects (at least one-fifth of our sun) nearby. “Nearby” in this case Means an area that is two thousand times as large as the distance between the earth and the sun.
