Now an international team of astronomers has finally observed the acceleration of protons within a shock wave. Using the Very Large Telescope in Paranal, Chile, and NASA's Chandra spacecraft, they measured the visible light and x-ray emissions of the remnant of a supernova about 8200 light-years away in the direction of the constellation Circinus.

现在，一个由天文学家组成的跨国研究小组终于观察到激波内部质子的加速情况，他们利用智利帕拉纳尔的甚大望远镜和美国国家航空航天管理局的钱德拉太空船，测量到了圆规座方向大约8，200光年处一颗超新星残骸发出的可见光和 X 射线。
