Black hole distorting its companion star, illustration
Conceptual illustration showing a black hole (centre) distorting its companion star (blue) in the star cluster NGC 1850, located 160, 000 light years away in the Large Magellanic Cloud. This distortion is due to the strong gravitational forces of the black hole. Scientists found this black hole by looking at the effects it had on the orbit of the companion star.This artistâ��s impression shows a compact black hole 11 times as massive as the Sun and the five-solar-mass star orbiting it. The two objects are located in NGC 1850, a cluster of thousands of stars roughly 160 000 light-years away in the Large Magellanic Cloud, a Milky Way neighbour. The distortion of the starâ��s shape is due to the strong gravitational force exerted by the black hole.� Not only does the black holeâ��s gravitational force distort the shape of the star, but it also influences its orbit. By looking at these subtle orbital effects, a team of astronomers were able to infer the presence of the black hole, making it the first small black hole outside of our galaxy to be found this way. For this discovery, the team used the Multi Unit Spectroscopic Explorer (MUSE) instrument at ESOâ��s Very Large Telescope in Chile.
