在黑暗和几乎没有月亮的夜空下，地球上的许多居民能够观看到今年的英仙座流星雨。8月13日，周日黎明前，在伊朗设拉子的一个长满草的山坡上，这些英仙座流星雨沿着夏季北部的银河系划过。用于构建合成图像的帧是在当地时间凌晨02:00至凌晨04:30之间，在每年流星雨活跃的高峰期附近拍摄的。但在这张夜空中，英仙座流星雨的光芒远高于相机的视野。但北方夏夜的爱好者仍然可以看到熟悉的星象。由明亮的恒星天津四、织女星和牛郎星组成的夏季三角横跨银河系的明亮带。

Under dark and mostly moonless night skies, many denizens of planet Earth were able to watch this year's Perseid meteor shower. Seen from a grassy hillside from Shiraz, Iran these Perseid meteors streak along the northern summer Milky Way before dawn on Sunday, August 13. Frames used to construct the composited image were captured near the active annual meteor shower's peak between 02:00 AM and 04:30 AM local time. Not in this night skyscape, the shower's radiant in the heroic constellation Perseus is far above the camera's field of view. But fans of northern summer nights can still spot a familiar asterism. Formed by bright stars Deneb, Vega, and Altair, the Summer Triangle spans the luminous band of the Milky Way.
