在这张8月13日凌晨拍摄的黎明前的天空景观中，大部分英仙座流星雨落在地球上。你可以很容易地识别英仙座流星雨的条纹。它们的轨迹似乎汇聚在一年一度的流星雨的辐射点上，英仙座的一个点，位于画面的顶部。这是地球天空的方向，沿着流星雨的母体，周期性的斯威夫特-塔特尔彗星的轨道望去。当然，这个场景是一个合成的，大约500个数字曝光的组合，以捕捉流星记录在一个基本帧曝光。但所有的照片都是在奥地利布尔根兰Mönchhof附近的一个风力发电场大约2.5小时内拍摄的。个别风力涡轮机塔上的红灯点缀在前景上。明亮的木星和金星在东方地平线上形成了壮观的近距离合相。

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.
