看流星雨最好的方法是什么？这个问题可能会在本周晚些时候英仙座流星雨的高峰期出现。有一件事很有帮助，那就是黑暗的天空，正如去年英仙座流星雨的特色合成图像所展示的那样。左图是在斯洛伐克非常黑暗的天空中拍摄的，而右图是在捷克共和国中等黑暗的天空中拍摄的，可以看到更多暗淡的流星。银河系的带连接了这两张协调的图像，而英仙座的流星雨在左边清晰可见。总而言之，许多暗淡的流星在明亮的天空中消失了。光污染正在缩小我们地球上黑暗天空的面积，尽管可以采用廉价的方法来解决这个问题。提交给APOD的英仙座流星雨：2018,2019,2020

What's the best way to watch a meteor shower? This question might come up later this week when the annual Perseid Meteor Shower peaks. One thing that is helpful is a dark sky, as demonstrated in the featured composite image of last year's Perseids. Many more faint meteors are visible on the left image, taken through a very dark sky in Slovakia, than on the right image, taken through a moderately dark sky in the Czech Republic. The band of the Milky Way Galaxy bridges the two coordinated images, while the meteor shower radiant in the constellation of Perseus is clearly visible on the left. In sum, many faint meteors are lost through a bright sky. Light pollution is shrinking areas across our Earth with dark skies, although inexpensive ways to combat this might be implemented.
