Full Moon Perseids

Explanation: The annual Perseid meteor shower was near its peak on August 13. As planet Earth crossed through streams of debris left by periodic Comet Swift-Tuttle meteors rained in northern summer night skies. But even that night’s nearly Full Moon shining near the top of this composited view couldn’t hide all of the popular shower’s meteor streaks. The image captures some of the brightest perseid meteors in many short exposures recorded over more than two hours before the dawn. It places the shower’s radiant in the heroic constellation of Perseus just behind a well-lit medieval tower in the village of Sant Llorenc de la Muga, Girona, Spain. Observed in medieval times, the Perseid meteor shower is also known in Catholic tradition as the Tears of St. Lawrence, and festivities are celebrated close to the annual peak of the meteor shower. Joining the Full Moon opposite the Sun, bright planet Saturn also shines in the frame at the upper right.

说明: 今年的英仙座流星雨之极大期落在8月13日。而随着地球穿过周期彗星史威福-塔托所留下的碎片流时,流星就洒在北半球的夜空中。在这幅摄于那晚的组合影像里,纵然接近满相的明月高悬在头顶附近,但它的月华也无法遮掩这群著名流星雨的所有流星迹。这幅组合自摄于破晓前2小时期间的多张短曝光照片之影像,记录了部分最明亮的英仙座流星。在这张影像里,位于英仙座里的流星雨辐射源,位在西班牙赫罗纳市圣洛伦索-德拉穆加村,这座月耀中世纪塔楼的后方。在中世纪,天主教称英仙座流星雨为圣洛朗的眼泪,而其庆典活动的高潮也落在这群流星雨的年度极大期附近。与满月为伍和太阳遥遥对望的,还有影像右上角的明亮土星。
