Signal from star being destroyed at supermassive black hole’s event
“It is very hard, the Spin of a Black hole limit, as the Spin effects occur only very close to the hole itself, where the gravity is extremely strong and it is hard to get a clear view”, explains Pasham, in a communication to the European space Agency ESA. A black hole is a collapsed star with a core so dense that it has near-unimaginable gravitational power.
Now researchers at MIT and elsewhere have pored through data from multiple telescopes’ observations of the event, and discovered a curiously intense, stable, and periodic pulse, or signal, of X-rays, across all datasets.
The crumbs left over from a supermassive black hole’s recent meal have allowed scientists to calculate the monster’s rotation rate, and the results are mind-boggling.
Astronomers back in 2014 were searching the night sky for something cool and found what they were looking for.

This is how Diego Simeone reacted to Alvaro Morata rumours Chelsea have four offers on their table for Alvaro Morata, who is determined to leave the club in the January transfer window . Chelsea striker Alvaro Morata has surely been one of the biggest flops that the Blues fans have seen in recent years.
Astronomers found evidence that the corona of a black hole is what drives its evolution. The black hole was a buzz saw, spinning fast enough to stretch the star into a rotating ring around the black hole’s event horizon, the point beyond which not even light can escape.
“That’s not super fast - there are other Black holes whose Spin is estimated to be close to 99 percent of the speed of light”, explains Pasham.
“There have already been measurements of spins from black holes that are actively accreting”, or acquiring more matter under the influence of gravity, the study’s first author Dheeraj Pasham, Einstein Postdoctoral Fellow at the MIT Kavli Institute, told Gizmodo.
