大约一周后英仙座流星雨将达到最大值。冰冷的岩石颗粒在进入地球大气层的过程中蒸发，会划过天空。这些颗粒是从斯威夫特-塔特尔彗星上脱落下来的。英仙座流星雨是由地球每年经过斯威夫特-塔特尔彗星的轨道造成的，通常是一年中最活跃的流星雨。虽然很难预测任何流星雨的活动水平，但在晴朗黑暗的天空中，观察者可能一分钟就能看到一颗流星。今年的英仙座流星雨在满月后几天达到高峰，所以一些微弱的流星将会消失在月球的天光中。一般来说，流星雨最好在远离灯光的放松位置观看。这是2015年英仙座流星雨在奥地利上空爆炸的一颗流星，它靠近我们银河系的中央带。

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.
