A published on quinta- Thursday (22) was able to obtain unprecedented information from the destruction of a star swallowed by a black hole. The observation of more detailed X-rays done to date to reveal what happens to the matter of the star to be devoured, and was reconstituted in the form of an animation
The intergalactic cataclysm reported in the study occurred on November 22, 2014, in a star on PGC043234 galaxy 295 million light years – not far in cosmic terms. It was the first made that a phenomenon of this magnitude was observed in a galaxy so close in recent decades, when there were instruments to study it
.
The light that lit the alarmed scientists was revealed by Wings-SN program, the Ohio State University, which maintains a sky scanning scheme search extreme events. Once detected the phenomenon, the telescope warned NASA, who observed what was happening in telescopes X-ray and gamma

According to scientists, what happened to the star in question is that it was destroyed by Black Hole through gravitational effects called tidal disruption . The cosmic monster in question is at the center of its galaxy, but is less than the black hole of our galaxy, the Milky Way

“The black hole rips the star and begins to swallow material quickly,” said Jelle Kaastra, the Space Research Institute of the Netherlands, one of the coauthors of the work, in a statement . “The black hole can not keep pace, then expels some of the material out.”
This material, as already predicted in theory end up handing in the form of ultra hot gas disk orbiting the the black hole. The high temperature of the gas observed now, indicates that part of this matter is on the verge of passing the event horizon, the boundary from which one can not escape from a black hole.
The telescopes Chandra, Swift and XMM-Newton, NASA did not have enough resolving power to see the structure formed by the destruction of the star. They were able, however, to obtain brightness data and frequency patterns sufficient detail for scientists to reconstruct the scene. From this idea was the animation made up
. According to scientists, the study of more events like this should allow the development of more accurate scenarios of what happens when black holes swallow stars. The study of the event in PGC043234 is the issue of this magazine this week “Nature”
