Dusty debris from periodic Comet Swift-Tuttle was swept up by planet Earth this week. Vaporized by their passage through the dense atmosphere at 59 kilometers per second, the tiny grains produced a stream of Perseid meteors. A bright, colorful Perseid meteor flash was captured during this 20 second exposure. It made its ephemeral appearance after midnight on August 12, in the moonless skies over the broad granite dome of Enchanted Rock State Natural Area, central Texas, USA. Below the Perseid meteor, trees stand in silhouette against scattered lights along the horizon and the faint Milky Way, itself cut by dark clouds of interstellar dust.

這周，來自週期性彗星Swift-Tuttle的塵埃碎片被地球吸引。這些微小顆粒在時速59公里的行進中，被密集的氣氛所蒸發，產生了一股流星雨，稱為英仙座流星。凌晨過後的8月12日，在美國德克薩斯州中央的Enchanted Rock State Natural Area廣闊的花崗岩圓頂上，捕捉到了明亮而色彩斑斕的英仙座流星的閃光。這道流星在星空中短暫出現，下面的樹木在地平線散布的燈光和微弱的銀河背景下，呈現出輪廓，銀河中還被星際塵埃的黑暗雲彩劃破。
