英仙座流星雨以其明亮和快速的流星而闻名，一年一度的英仙座流星雨从英仙座的光芒中来到地球的天空。北半球夏季流行的天体奇观是由周期彗星109P/斯威夫特-塔特尔的轨道上抛射出来的尘埃颗粒在地球稠密的大气层中蒸发，在夜空中留下短暂但美丽的条纹。这张合成图像拍摄于8月12日，接近流星雨活动的高峰期，记录了两颗明亮的英仙座流星和一颗流星在瑞典沿海村庄Grisslehamn附近的水样反射。几乎和牛郎星一样明亮，牛郎星是场景中最亮的恒星，流星出现在银河系暗淡的漫反射背景中。今年，流星雨的活动高峰与新月重合，所以英仙座流星雨的闪光不会因明亮的月光而减弱。对于许多天文观测者来说，这个明亮的英仙座流星之夜伴随着他们在期待已久的日食中看到新月的剪影。成长画廊：2026年8月12日的日食

Known for its bright and fast meteors, the annual Perseid Meteor Shower comes to planet Earth's skies from a radiant in the heroic constellation Perseus. The popular northern summer celestial spectacle is created as grains of dust cast off along the orbit of periodic comet 109P/Swift-Tuttle vaporize in Earth's dense atmosphere, tracing brief, but beautiful streaks through the night. Taken near the shower's peak of activity on August 12, this composite image recorded two bright perseid meteors and one meteor's watery reflection from a location near the coastal village of Grisslehamn, Sweden. Almost as bright as Altair, brightest star on the scene, the meteors appear along with the faint, diffuse background of the Milky Way. This year, the shower's peak activity coincided with a New Moon, so perseid meteor flashes were undiminished by bright moonlight. And for many skywatchers, this night of bright perseid meteors followed their viewing of the silhouette of the New Moon in a much anticipated solar eclipse.
