Explanation: Rounding the Sun on July 3rd and currently headed for the outer Solar System, Comet NEOWISE (C/2020 F3) has been growing brighter in the predawn skies of planet Earth. From low Earth orbit it also rises before the Sun, captured above the approaching glow along the eastern horizon in this snapshot from the International Space Station on July 5. Venus, now Earth’s morning star is the brilliant celestial beacon on the right in the field of view. Above Venus you can spot the sister stars of the more compact Pleiades cluster. Earthbound skygazers can spot this comet with the unaided eye, but should look for awesome views with binoculars.

说明：于7月3日旋绕过太阳、目前踏上返回太阳系外围之旅的NEOWISE彗星（C/2020 F3 尼欧外兹），在地球日出前的天空，亮度不断增加。在这幅7月5日摄于国际空间站的单张影像里，从低地球轨道看出去，这颗彗星比太阳早些升起，并沈浸在东方地平线上空的晨曦中。这片视野右侧的明亮天体，是以地球晨星之姿现身的金星。金星的上方，则有相对紧实的昴宿星团和它的成员星。地面上的观星者，用肉眼就能找到这颗彗星，不过使用双筒望远镜更能见到它的风华。
