dark sky background的意思|示意

Dark clouds flow across the sky, sometimes from different directions, sometimes blocking background starlight, but other times causing stars to appear to flare as they move in front.

云朵横穿过天空，时而来自不同的方向，时而遮蔽了星光熠熠的蓝色幕布，有时他们移到恒星的前面，忽厚忽薄的云使得星星一闪一闪的发亮。

Even during a thunderstorm, I saw the dark night outside a bar is under the lightning, the sky against the background of dark purple like those old stars.

即使雷雨交加，我看到外面漆黑的夜色之下是一条条闪电，把天幕映衬的暗紫如同那些老去的恒星。
