Star leaves the galaxy like a cork bottle
Astronomers have discovered a super fast double star, which flies out of our galaxy at a speed of more than 800 kilometers per second.
Hyperspeed stars were first seen by people in the early 2000s: their speed relative to the center of the Galaxy reached 500 kilometers per second, and this rate was enough to "Get rid" of the star attraction of the system and go to a free intergalactic space.
In 2007, Warren Brown found the star, which is equal to the speed of 850 kilometers per second relative to the sun, and it's the fastest in today's day star - main sequence star.
Astronomers believe that some stars are accelerated to such insane speeds due to gravitational interaction with the supermassive black hole at the center of the galaxy. Therefore, the study of the orbits of stars SuperSpeed allows determining the properties of these black holes and dark matter.
However, we have shown that the current star could not disperse the black hole, because the analysis clearly showed that it did not fly from the center of the galaxy. Then how she flew, how did and how could accelerate - these questions scientists have yet to find the answers.
