在天上，有一場叫做Perseid流星雨的特別表演即將發生！每年，當地球經過一顆名叫Comet Swift-Tuttle的彗星時，就會看到這些流星。它們是一小粒小小冰冷的石頭，當它們進入地球的天空時，會發光並像閃電一樣劃過夜空！今年的Perseid流星雨將在滿月之後來到，所以有些微弱的流星可能會被明亮的月光遮住。想要觀賞這場宇宙秀的朋友，可以選擇在一個沒有太多燈光的地方躺下，這樣會更容易看見流星哦！這張圖片是2015年Perseid流星雨中，在奧地利上空爆炸的流星，旁邊還有我們的銀河系，真美麗！
原文:
In about a week the Perseid Meteor Shower will reach its maximum. Grains of icy rock will streak across the sky as they evaporate during entry into Earth’s atmosphere. These grains were shed from Comet Swift-Tuttle. The Perseids result from the annual crossing of the Earth through Comet Swift-Tuttle’s orbit, and are typically the most active meteor shower of the year. Although it is hard to predict the level of activity in any meteor shower, in a clear dark sky an observer might see a meteor a minute. This year’s Perseids peak just a few days after full moon, and so some faint meteors will be lost to the lunar skyglow. Meteor showers in general are best seen from a relaxing position, away from lights. Featured here is a meteor caught exploding during the 2015 Perseids above Austria next to the central band of our Milky Way Galaxy.
