I caught a very close and rare moment of contact between a giant red star A black hole, By NASA’s technologyESA The strong, with the discovery of a major chapter in a cosmic saga likely to last for a trillion years, and the deadly celestial event unfolds in the galaxy GSN 069 – About 250 million light-years from Earth.
The size of the mentioned black hole is 400 thousand times the mass of the sun, which makes it small, according to the criteria of the massive black hole, but it is still terrifying in size, according to Russia today.
Meanwhile, the red giant, trapped in the gravity of the black hole, stripped its outer layers of hydrogen, leaving only the star’s core – the white dwarf – to reveal its narrow-field escape through X-ray bursts..
The black hole escaped–
Andrew King of the University of Leicester in the United Kingdom, who studied the data from the European Space Agency and NASA, said: “In my interpretation of X-ray data the white dwarf survived, but it did not escape. He is now stuck in an elliptical orbit around the black hole, and makes one trip once every 9 hours. “
In other words, the remaining white dwarf revolves around its attacker, 3 times a day, as the black hole eats up the layers the closer the star gets too close.
And every time the black hole tears more material from the star, it releases a series of X-rays that can be seen by NASA’s Chandra X-ray Observatory, andXMM-Newton Of the European Space Agency.
Researchers also expect that gravitational waves will be launched by the black hole and the white dwarf, while continuing the dance of death, and although the star’s loss of mass will cause its orbit to rotate and expand, scientists predict only one result: an inevitable death.
Scientists have documented countless cases of black holes tearing stars into pieces, but there were very few such semi-survival tales.
There are many theories as to why such events are often not observed: either that more of these massive stars take too long to complete their orbits around the black hole so that X-ray explosions can be observed, or that the majority of black holes present are very large and very lethal, without capacity On monitoring the catastrophic event.
