Light echoes: the reflections of stellar explosions onto interstellar dust.

光回声：恒星爆炸对星际尘埃的反射。

I am adapting the same models that detect plumes in city images to detect light echoes in images of the sky.

我正在调整检测城市图像中羽流的相同模型，以检测天空图像中的光回波。

" To hear ringing (ringing) in your ears" is to have sort of a light, echoing noise that shouldn't really be there.

“听到耳鸣（响铃）” 是指有一种轻微的、回声的噪音， 实际上不应该存在。
