Everyone knows that black holes have an “insatiable appetite.” Because these objects are so high density that even light cannot escape their gravitational attraction, they emit powerful bursts of x-ray radiation, creating what is known as the cosmic x-ray background, writes brains2.biz.
Now the data collected spectroscopic telescope NASA (NuStar), finally, will help scientists to determine exactly why black holes emit x-rays, thus making a significant step towards space exploration.
Black holes emit x-rays when the gas and dust around them are heated and accelerated to the speed of light. As the black hole grows, the number of x-ray radiation increases. It is not surprising that huge black holes that reside in the centers of most galaxies, including our own, emit more powerful x-rays than single black holes in the dark void of space.
Thanks to NuStar, scientists will be better able to study the structure of black holes and understand their purpose in the cosmos.
