黃昏下的地球
Planet Earth at Twilight
發表日期:2024-12-27
在這幅美麗的作品中,海洋和雲朵在我們美麗的地球上空交織成一幅美麗的畫卷。取而代之的是,陰影線或終點線是漫無邊際的,顯示了我們所經歷的黃昏向黑暗的逐漸過渡。太陽從右邊照亮了整個場景,雲層頂端反射出柔和的紅光,這些紅光是經過塵埃對流層過濾的,對流層是地球孕育大氣層的最底層。沿著天邊的上邊緣可以看到一個清晰的高空層,散射著藍色的陽光,漸漸消失在漆黑的太空中。這張照片是從高度為 211 海里的國際空間站上拍攝的。當然,您也可以在家裡檢視 "現在的地球"。
原文:No sudden, sharp boundary marks the passage of day into night in this gorgeous view of ocean and clouds over our fair planet Earth. Instead, the shadow line or terminator is diffuse and shows the gradual transition to darkness we experience as twilight. With the Sun illuminating the scene from the right, the cloud tops reflect gently reddened sunlight filtered through the dusty troposphere, the lowest layer of the planet's nurturing atmosphere. A clear high altitude layer, visible along the dayside's upper edge, scatters blue sunlight and fades into the blackness of space. This picture was taken from the International Space Station orbiting at an altitude of 211 nautical miles. Of course from home, you can check out the Earth Now.
