在美麗的夜空中，8月13日的清晨，有許多流星像小星星一樣快速滑過地球。這些流星叫做Perseid流星，每當它們出現時，大家就知道是這個特別的時刻了。你可以看到這些流星的尾巴，彷彿都聚集起來，指向星座Perseus的方向。這個星座就像一位英雄一樣，位於畫面的上方。流星的來臨是因為太空中的一次旅行，這是來自於名為Comet Swift-Tuttle的彗星。這幅畫面實際上是用500張數碼照片拼接而成的，所有的照片都是在大約2.5小時內拍的，拍攝地點是在奧地利的Mönchhof風電場。你可以看到前景的風電塔上有紅色的燈光，這讓夜空更加迷人。而在東方的地平線上，明亮的行星木星和金星也正翩翩起舞，為這個畫面增添了光彩。
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.
