Explanation: This sight was worth getting out of bed early. Comet C/2020 F3 (NEOWISE) has been rising before dawn during the past week to the delight of northern sky enthusiasts awake that early. Up before sunrise, the featured photographer was able to capture in dramatic fashion one of the few comets visible to the unaided eye this century, an inner-Solar System intruder that might become known as the Great Comet of 2020. The resulting video details Comet NEOWISE from Italy rising over the Adriatic Sea. The time-lapse video combines over 240 images taken over 30 minutes. The comet is seen rising through a foreground of bright and undulating noctilucent clouds, and before a background of distant stars. Comet NEOWISE has remained unexpectedly bright, so far, with its ion and dust tails found to emanate from a nucleus spanning about five kilometers across. Fortunately, starting tonight, northern observers with a clear and dark northwestern horizon should be able to see the sun-reflecting interplanetary snowball just after sunset.

说明：这种景观值得早起聆赏。在上个星期，清晨天空中的NEOWISE彗星（C/2020 F3），是北半球早起的星空爱好者的新宠。这部主题影片的摄影者就是在日出前早起，以扣心心弦的方式拍摄本世纪少数肉眼可见的彗星，而这个太阳系内围的访客，将来或许会有2020年大彗星的令名。这部摄于意大利的影片，清楚呈现NEOWISE彗星如何在亚得里亚海的上空向上攀升。这部缩时影片，则组合自摄于30分钟期间的240多张照片。影片中，位在前景明亮波浪状夜光云后方、遥远背景恒星前方的NEOWISE彗星，不断向上升起。 截自目前为止，NEOWISE彗星仍然出奇的明亮，并曳着源自约5公里宽彗核的离子尾和尘尾。北半球的观星者有福了！在数天之后，拥有幽暗低平西北地平线视野的北半球观星者，在刚日落后，就能见到这颗不停反射阳光的行星际雪球。
