这两条线有什么不同？右上方的条纹是土人山-阿特拉斯彗星，它显示了令人印象深刻的尘埃尾巴。这颗彗星是一个又大又脏的冰山，它进入了太阳系内部，在太阳的温暖下释放出气体和尘埃。左下方的条纹是一颗流星，显示出令人印象深刻的蒸发轨迹。这颗流星是一颗小而冷的岩石，它进入地球大气层后，由于分子碰撞而变暖，从而释放出气体和尘埃。这颗流星可能曾经是彗星或小行星的一部分，也许后来构成了彗星或小行星尾巴的一部分。这颗流星一闪而过，只是在记录彗星长尾巴的一系列曝光中偶然发现的。这张特色图片是一个多月前在中国四川省拍摄的。图片集：2024年的冢山彗星

How different are these two streaks? The streak on the upper right is Comet Tsuchinshan-Atlas showing an impressive dust tail. The comet is a large and dirty iceberg that entered the inner Solar System and is shedding gas and dust as it is warmed by the Sun's light. The streak on the lower left is a meteor showing an impressive evaporation trail. The meteor is a small and cold rock that entered the Earth's atmosphere and is shedding gas and dust as it is warmed by molecular collisions. The meteor was likely once part of a comet or asteroid -- perhaps later composing part of its tail. The meteor was gone in a flash and was only caught by coincidence during a series of exposures documenting the comet's long tail. The featured image was captured just over a month ago from Sichuan Province in China. Gallery: Comet Tsuchinshan-ATLAS in 2024
