Supermassive black hole rotates at half light speed


(Digital India Preview) Black holes are some of the most fascinating features of our universe, but they are also not very well understood. Studying distant black holes in any great detail is very difficult due to the fact that nothing, including light, can escape its reach as it gets very close. Now a black hole about 290 million light-years from Earth gives scientists the rare opportunity to measure their speed, and the numbers are staggering.

Researchers who used the automated Survey for Supernovae telescope network detected a "blast of light" from a specific point in the sky in 2014. After more detailed examination and observations using other instruments, scientists determined that the X-ray energy explosion was coming from a star, however not just any star. This star was in the middle of being torn by a black hole.

The star itself had no hope of escaping the black hole as it reached its event horizon – the area around a black hole from which nothing can escape – but the X-rays of the fractured body of the star were still visible while the debris circulated. the super-dense body.
