In the late 1990s satellites used upgraded optics and x-ray detectors to finally capture a gamma-ray burst afterglow.

在90年代后期，使用改进过的光学器件和X射线探测器的人造卫星终于捕获到了伽玛射线爆发的余辉。

Within hours, ground-based telescopes pinpointed the position, and for the first time saw the fading afterglow of a GRB.

几个小时后，地面望远镜确定了位置，第一次看到了 GRB 的余辉。

The next day, I wrote more thank-yous - and felt the same afterglow.

第二天，我又写了更多的感谢信——也体会到同样的美好感受。

Eastwards the snow-peaks burned in the afterglow.

向东，雪峰在余辉中燃烧。

A golden afterglow throbbed in the west, but the country already looked empty and mournful.

一片金色的余晖在西边悸动， 但这个国家已经显得空旷而凄凉。

This was the first image of the cosmic microwave background: the afterglow of the Big Bang.

这是宇宙微波背景的第一张图片：大爆炸的余辉。

There was a faint afterglow in the sky beyond the chimneys; a light twinkled at one of the upper windows.

烟囱外的天空中有一丝微弱的余晖。 楼上的一扇窗户闪烁着灯光。

The last few pages I read by the light of the full moon, that of afterglow having till then sufficed me.

最后几页是我在满月的光辉下阅读的，直到那时，余晖才让我感到满足。

The only hope was to have a faster response time, so that any fading “afterglow” from an event might be caught before it became invisible.

唯一的希望是有更快的反应时间，这样任何从一个事件中消失的“余光”就可以在它变得无形之前被捕捉到。

Scientists hope that by studying the Cosmic Microwave Background (the afterglow of the Big Bang) and the distribution of galaxies, they can gain deeper insights into these elusive phenomena.

科学家希望通过研究宇宙微波背景（大爆炸的余辉）和星系的分布，能够更深入地了解这些难以捉摸的现象。
