Evidence of Jet in Milky Ways Black Hole found by NASAs Chandra X-Ray. We were very eager to find a jet from Sgr A* because it tells us the direction of the black holes spin axis. This gives us important clues about the growth history of the black hole, said California University. Previous studies, using a variety of telescopes, suggested there was a jet, but these reports including the orientation of the suspected jets often contradicted each other and were not considered definitive. Scientists think jets are produced when some material falling toward the black hole is redirected outward. Since Sgr A* is presently known to be consuming very little material, it is not surprising the jet appears weak. A jet in the opposite direction is not seen, possibly because of gas or dust blocking the line of sight from Earth or a lack of material to fuel the jet.
