The cosmic background radiation is a remnant from the Big Bang.

宇宙的背景辐射是大爆炸的遗迹。

And we detect this cosmic background radiation coming more or less evenly from all directions, forming a background beyond the stars.

我们发现这种“宇宙背景辐射”在各个方向几乎都是均匀的，形成了恒星外的背景。

These quasar jets are formed when electrons emitted from a black hole impact with cosmic background radiation left by the big bang, giving astronomers clues about the conditions in the early universe.

这些类星体的河外星系是由当黑洞所发射的电子与大爆炸所遗留下来的宇宙背景辐射碰撞后所形成的，它为天文学家提供了关于早期宇宙的线索。
