Explanation: A comet has suddenly become visible to the unaided eye. Comet C/2020 F3 (NEOWISE) was discovered in late March and brightened as it reached its closest approach to the Sun, inside the orbit of Mercury, late last week. The interplanetary iceberg survived solar heating, so far, and is now becoming closer to the Earth as it starts its long trek back to the outer Solar System. As Comet NEOWISE became one of the few naked-eye comets of the 21st Century, word spread quickly, and the comet has already been photographed behind many famous sites and cities around the globe. Featured, Comet NEOWISE was captured over Lebanon two days ago just before sunrise. The future brightness of Comet NEOWISE remains somewhat uncertain but the comet will likely continue to be findable not only in the early morning sky, but also next week in the early evening sky.

说明: 天空有颗突然增亮到肉眼可见的彗星。在今年3月底发现的C/2020 F3 (NEOWISE彗星)，随着它往太阳靠，亮度也随之增加。它在上星期运行到水星轨道之内。截到目前为止，这团行星际”冰堡”在太阳热能的摧残下存活了下来，而在返回太阳系外围的长长旅途中，最近来到地球附近。当彗星NEOWISE成为21世纪少数的裸视彗星时，讯息迅速传开，让这颗彗星留下许多与地球著名的景点、城市及其他地貌的合影。在上面这幅摄于2天前的主题影像里，日出前的清晨星空中，NEOWISE彗星悬在黎巴嫩的上空。NEOWISE彗星未来的亮度仍然难以预测；不过不论如何，目前可见在清晨天空找到这颗彗星的身影，下星期起，它会移到初入晚的夜空中。
