NuSTAR Probes Black Hole Jet Mystery

Reviewing back...

We know if everything whom passes in front of black hole can be eaten by black hole, such as vacuum cleaner or hover. But do you know if it doesn't eat everything? Of course you don't, maybe some of you know it, but in this article from www.nasa.gov said if a black hole doesn't eat everything like ravenous eaters that is a small portion of material which it will gets shot back out in powerful jets of hot gas, called plasma, if the small portion gets into black hole and it can wreak havoc on their surroundings. Scientists have long debate about where and how this happens in the jet. However, using NASA's NuSTAR space telescope and ULTRACAM, scientists from Spain have been able to measure the distance called Acceleration Zone that particles in jets travel before they "turn on" and become bright sources of light. Making these measurements wasn't easy.

The best theory scientists have to explain these results is that the X-ray light originates from material very close to the black hole. Strong magnetic fields propel some of this material to high speeds along the jet. The results also appear to connect with scientists' understanding of supermassive black holes, much bigger than the ones in this study. The results also appear to connect with scientists' understanding of supermassive black holes, much bigger than the ones in this study. The next steps are to confirm this measured delay in observations of other X-ray binaries, and to develop a theory that can tie together jets in black holes of all sizes.
