主要是英仙座流星雨
Mostly Perseids

在這幅 8 月 13 日凌晨錄製的黎明前的天際景象中，大部分英仙座流星雨都落在了地球上。你可以很容易地識別英仙座流星群。它們的軌跡似乎都匯聚在一年一度的流星雨輻射點上，即位於畫面上方的英仙座。這是地球天空中流星雨母體--週期性彗星斯威夫特-塔特爾的軌道方向。當然，這個場景是合成的，是大約 500 次數字曝光的組合，以捕捉流星，並以單個基本幀曝光。但所有的曝光都是在奧地利布林根蘭州蒙希霍夫附近的一個風力發電廠進行的，歷時約 2 . 5 小時。各個風力渦輪機塔上的紅燈點綴著前景。明亮的木星和金星在東邊的地平線上相會，蔚為壯觀。
原文：In this predawn skyscape recorded during the early morning hours of August 13, mostly Perseid meteors are raining down on planet Earth. You can easily identify the Perseid meteor streaks. They're the ones with trails that seem to converge on the annual meteor shower's radiant, a spot in the heroic constellation Perseus, located off the top of the frame. That's the direction in Earth's sky that looks along the orbit of this meteor shower's parent, periodic Comet Swift-Tuttle. Of course the scene is a composite, a combination of about 500 digital exposures to capture meteors registered with a single base frame exposure. But all exposures were taken during a period of around 2.5 hours from a wind farm near Mönchhof, Burgenland, Austria. Red lights on the individual wind turbine towers dot the foreground. In their spectacular close conjunction, bright planets Jupiter and Venus are poised above the eastern horizon.
