這兩條條紋有什麼不同？ 右上方的條紋是月琴山-阿特拉斯彗星，顯示出令人印象深刻的塵埃尾跡。這顆彗星是進入太陽系內部的一座又大又髒的冰山，在太陽光的照耀下變得溫暖，正在脫落氣體和塵埃。左下方的條紋是一顆流星，顯示出令人印象深刻的蒸發痕跡。 這顆流星是一塊小而冷的岩石，進入地球大氣層後，由於分子碰撞而變暖，正在脫落氣體和塵埃。 這顆流星很可能曾經是彗星或小行星的一部分--也許後來構成了彗尾的一部分。 這顆流星轉瞬即逝，只是在記錄彗星長尾的一系列曝光中被巧合地捕捉到了。這張照片是一個多月前在中國四川省拍攝的。 相簿： 2024 年的月琴山-ATLAS 彗星
原文：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
