Beautiful Comet Nishimura

Explanation: This scene would be beautiful even without the comet. By itself, the sunrise sky is an elegant deep blue on high, with faint white stars peeking through, while near the horizon is a pleasing tan. By itself, the foreground hills of eastern Slovakia are appealingly green, with the Zadňa hura and Veľká hora hills in the distance, and with the lights of small towns along the way. Venus, by itself on the right, appears unusually exquisite, surrounded by a colorful atmospheric corona. But what attracts the eye most is the comet. On the left, in this composite image taken just before dawn yesterday morning, is Comet Nishimura. On recent mornings around the globe, its bright coma and long ion tail make many a morning panoramic photo unusually beautiful. Tomorrow, C/2023 P1 (Nishimura) will pass its nearest to the Earth for about the next 434 years.

说明: 即使没有彗星，这片视野也很美丽。在视野里，上层的日出时分天空是优美的深蓝色，隐约露出泛白的星星，而地平线附近的天空则渲染着令人愉悦的棕褐色。前景为斯洛伐克东部的翠绿山峦，远方有Zadňa hura山、Veľkáhora山、及沿途小镇的灯火。视野右侧的金星，周围环拱着色彩斑斓的大气华，因此看来异常华丽。尽管如此，视野里最吸睛的还是彗星。在这幅摄于昨晨黎明前的组合影像里，左侧可见到西村彗星。最近在全球各地的清晨，它曳着明亮的彗发和颀长的离子尾，让许多清晨的全景照片变得格外美丽。在明天，彗星C/2023P1（西村）将来到后续434年期间最接近地球的位置。
