X-Ray Light From Black Holes


June 14, 2013 — It is a mystery that has stymied astrophysicists for decades: how do black holes produce so many high-power X-rays?

In a new study, astrophysicists from The Johns Hopkins University, NASA and the Rochester Institute of Technology conducted research that bridges the gap between theory and observation by demonstrating that gas spiraling toward a black hole inevitably results in X-ray emissions.

The paper states that as gas spirals toward a black hole through a formation called an accretion disk, it heats up to roughly 10 million degrees Celsius. The temperature in the main body of the disk is roughly 2,000 times hotter than the sun and emits low-energy or "soft" X-rays. However, observations also detect "hard" X-rays which produce up to 100 times higher energy levels.


Black Holes, Science Fiction's most interesting past time. Many of us see Black Holes as an infallible force in our universe. You can make a Black Hole, but you can't really break one. So what exactly is happening inside of a black hole?

That's a very complicated question, one I unfortunately don't have the time right now to answer. However, this article does point us in the right direction of what exactly is happening with a black hole. Many physicists believe Black Holes lead to another universe entirely, the other side appearing as a "White Hole" or another Big Bang.

If the black hole on our side emits so many X-Rays though, where is all of this excess energy coming from? Black Holes are supposed to suck things in right? Especially since Black Holes have been known to capture Light as well. Perhaps the answer lies in better understanding how Quasars work, and why something so powerful could fail to store all of that energy.

In any case, finding X-Rays emitting from Black Holes still raises a lot of questions. Ones we may need to know more to answer.
