这张照片的美是有层次的。最下面一层是西班牙巴塞罗那风景如画的曼莱乌村。六分钟的曝光使车灯变成条纹。下一层是欧洲著名的比利牛斯山——贝尔蒙特山。下一个是巨大的雷暴从经典形状的铁砧云发出。长时间曝光可以捕捉到许多复杂的闪电。最后，在顶端和最遥远的地方是星星。在这里，几分钟的曝光使星星变成了轨迹。这种尾随效应是由地球自转引起的，而轨迹的曲率表明了它们与地球北极的距离。拍摄于六月初的日落之后，闪电风暴很快就消失了。不过，只要地球自转，恒星就会继续绕着极点转——肯定会持续数十亿年。

The beauty in this image comes in layers. On the bottom layer is the picturesque village of Manlleu in Barcelona, Spain. The six-minute exposure makes car lights into streaks. The next layer is a mountain -- Serra de Bellmunt -- of Europe's famous Pyrenees. Next up is a tremendous lightning storm emanating from a classically-shaped anvil cloud. The long exposure allowed for the capture of many intricate lightning bolts. Finally, at the top and furthest in the distance are stars. Here, the multi-minute exposure made stars into trails. The trailing effect is caused by the rotation of the Earth, and the curvature of the trails indicates their distance from the north spin pole of the Earth above. Taken after sunset in early June, the lightning storm soon moved off. The stars, though, will continue to circle the pole for as long as the Earth spins -- surely billions of years into the future.
