这是一个不寻常的天空。这并不罕见，因为在左边的图像中可以看到银河系的中央带。大多数黑暗的天空显示了银河系的一部分。这并不罕见，因为在右上方可以看到明亮的流星。上周英仙座流星雨期间拍摄的许多照片都显示有流星，尽管这次英仙座流星雨特别明亮。这个天空并不罕见，因为在右下角可以看到红色精灵。虽然这种类型的闪电在过去的几十年里才被注意到，但精灵的图像正变得越来越普遍。这片天空并不罕见，因为这颗新星就在图像中心上方。每隔几年就会出现一颗足够明亮的新星，用肉眼就能看到，这张照片是一周前发现的蛇夫座新星RS。然而，最不寻常的是，在一个晚上，在一片天空中，同时捕捉到所有这些东西。墨西哥萨卡特卡斯上空出现了不寻常的天空。著名的APOD图片提交：英仙座流星雨2021
查看原文解释
This was an unusual sky. It wasn't unusual because of the central band the Milky Way Galaxy, visible along the image left. Most dark skies show part of the Milky Way. It wasn't unusual because of the bright meteor visible on the upper right. Many images taken during last week's Perseid Meteor Shower show meteors, although this Perseid was particularly bright. This sky wasn't unusual because of the red sprites, visible on the lower right. Although this type of lightning has only been noted in the past few decades, images of sprites are becoming more common. This sky wasn't unusual because of the nova, visible just above the image center. Novas bright enough to be seen with the unaided eye occur every few years, with pictured Nova RS Ophiuchus discovered about a week ago. What was most unusual, though, was to capture all these things together, in a single night, on a single sky. The unusual sky occurred above Zacatecas, Mexico.
