Remembering NEOWISE

Explanation: 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.

说明: 在刚过去的去年7月,如你看得到北斗七星,就能在夜空里找到新智彗星。当时在日落后,地球的住民能在西北地平线上的上方,以及著名北斗七星的斗杓下方,找到这颗裸视彗星。这颗彗星看似带尾巴的弥漫“星星”,于2020年7月23日此彗星最近地球的期间,在这片摄于捷克的天空景观里,它的彗尾并不是很长。在记录彗星C/2020 F3(新智)的照片,常见的景观为这颗彗星宽广的尘埃,以及清楚分隔而且延伸超出视力可见范围的泛蓝离子尾。而世界各地的观星者都为能目睹新智彗星,这颗来自太阳系外围的意外访客而欣喜不已。
