Scientists found a rare star has escaped from a Supermassive Black hole..
Scientists have traced the star named S5-HVS1 which ejected out of the supermassive black hole Sagittarius A* (Sgr A*) and has been moving at a massive speed of 1,700 kilometers per second since then.
Scientists say that this is the only star that escaped from the force of such massive black hole. Until we know that nothing can escape from black holes gravitational pull not even light , but it's the first time that a star is kicked out of Sagittarius A*.
According to a research paper titled ‘The Great Escape: Discovery of a nearby 1700 km/s star ejected from the Milky Way by Sgr A*‘, the star has already spent around 4.8 million years on a lonely journey in the space after it was kicked away from the Sagittarius A* black hole. “When integrated backwards in time, the orbit of the star points unambiguously to the Galactic Centre, implying that S5-HVS1 was kicked away from Sgr A* with a velocity of ∼ 1800 km/s,” the researchers wrote in the paper.
“With the S5-HVS1 ejection velocity being almost twice the velocity of other hyper-velocity stars previously associated with the Galactic Centre, we question whether they have been generated by the same mechanism or whether the ejection velocity distribution has been constant over time” the research paper read.
