那是去年七月。如果你能看到北斗七星，你就能在夜空中找到NEOWISE彗星。日落之后，北方的居民可以在那个著名的天上厨房用具的碗下面和西北地平线上寻找这颗彗星。这颗彗星看起来像一颗带有尾巴的模糊“恒星”，尽管它的尾巴可能没有这张令人难忘的天空图那么长，这张照片是在2020年7月23日，在彗星最接近地球的地方拍摄的。C/2020 F3 （NEOWISE）的照片经常显示彗星宽阔的尘埃尾巴和较暗但独立的蓝色离子尾巴，延伸到眼睛无法跟随的地方。世界各地的天文学家都很高兴地目睹了NEOWISE彗星，这颗来自外太阳系的意外访客。值得注意的彗星NEOWISE图像2020:7月31日30日，29日，28日，27日，26日，25日，24日

It was just last July. If you could see the stars of the Big Dipper, you could find Comet NEOWISE in your evening sky. After sunset denizens of the north could look for the naked-eye comet below the bowl of that famous celestial kitchen utensil and above the northwestern horizon. The comet looked like a fuzzy 'star' with a tail, though probably not so long a tail as in this memorable skyview recorded from the Czech Republic on July 23th, 2020, near the comet's closest approach to planet Earth. Photographs of C/2020 F3 (NEOWISE) often did show the comet's broad dust tail and fainter but separate bluish ion tail extending farther than the eye could follow. Skygazers around the world were delighted to witness Comet NEOWISE, surprise visitor from the outer Solar System. Notable Comet NEOWISE Images 2020: July 31 30, 29, 28, 27, 26, 25, 24
