Electric Night

Explanation: It may appear, at first, like the Galaxy is producing the lightning, but really it's the Earth. The featured nighttime landscape was taken from a southern tip of the Italian Island of Sardinia in early June. The foreground rocks and shrubs are near the famous Capo Spartivento Lighthouse, and the camera is pointed south toward Algeria in Africa. In the distance, across the Mediterranean Sea, a thunderstorm is threatening, with several electric lightning strokes caught together during this 25-second wide-angle exposure. Much farther in the distance, strewn about the sky, are hundreds of stars in the neighborhood of our Sun in the Milky Way Galaxy. Furthest away, and slanting down from the upper left, are billions of stars that together compose the central band of our Milky Way.

说明:乍一看,似乎是银河正在产生闪电,但实际上是地球。这幅精彩的夜景影像是在6月初从意大利撒丁岛南端拍摄的。影像前景中的岩石和灌木位于著名的斯巴提文多角灯塔附近,而照相机则向南、朝着非洲的阿尔及利亚方向眺望。在这幅曝光时长为25秒的广角影像中,地中海远处的海面上正在发生一场雷暴,并同时产生了数道闪电。在更遥远的远方,银河系中邻近太阳的数百颗恒星布满了天空。在最远处、从左上角向下倾斜分布的数十亿颗恒星共同构成了我们银河系的中央带。
