当观看这个高空气球视频我偶然发现了一件奇怪的事情:转到6:08,看到黑色的天空突然变成蓝色,因为相机位置不同。这是一张从87,000英尺(26.5公里)高空拍摄的照片,尽管(或因为?)不再面向太阳,但整个天空突然变成了蓝色。通常,在这样的近空间视频中,我观察到相反的情况:在太阳周围,黑色的天空变得有点蓝,这显然是由于在仰望太阳时,非常稀薄的大气散射了光线。但到目前为止,我还没有看到相反的情况,除了我看过一些关于相同高度的天空颜色的视频(其中包括上升火箭机载摄像机拍摄的视频)。< / p >
Why does the otherwise black sky suddenly turn blue in the footage and what does the sky really look like around 87,000 ft to the human eye (I've never been to these altitudes myself)?
I guess the camera captures quite a good impression on how dark the upper parts of the atmosphere are. There is almost nothing left that can scatter the light and this results in very dark conditions.
