The X-ray jet in the upper left extends for about 13, 000 light years away from the black hole.
左上的X射线喷流从黑洞延伸到13000光年远。
When particles in the jet strike a photon of visible or infrared light, they cause the photon to jump up in energy and become a gamma ray.
当喷流中的粒子撞击到可见光或者红外波长上的光子，将导致光子能量跃迁，形成伽玛射线。
In the experiment, the X-ray testing system takes pictures of the jet formatting and stretching. According to the pictures, we can calculate the jet tip average velocity.
实验工作用X光拍摄射流形成过程和射流运动姿态，通过X光片测出射流头部平均速度；
