路邊那道奇怪的光是什麼?繞太陽執行的塵埃。在一年中的某些時候,太陽系內部有一條反射太陽光的塵埃帶會在日落之後或日出之前顯現出來,這就是黃道十二宮光。 儘管人們仍在研究這種塵埃的來源,但一種主要的假設認為,黃道帶塵埃主要來自微弱的木星眷屬彗星,並緩慢地螺旋進入太陽。最近對歐空局機器人 "羅塞塔 "號飛船訪問過的 67 P 彗星散發的塵埃進行的分析支援了這一假設。 圖為在攀登通往西班牙加那利群島泰德國家公園的道路時,日落後不久,遠處出現了一個明亮的三角形黃道十二宮光。該場景拍攝於 2019 年 6 月 21 日,其中包括明亮的軒轅黃帝星,它是獅子座的α星,位於中央偏左的位置。蜂巢星團(M 44 )位於中心下方,更靠近地平線,也沉浸在黃道十二宮的光芒之中。
原文:What's that strange light down the road? Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset -- or just before sunrise -- and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and slowly spirals into the Sun. Recent analysis of dust emitted by Comet 67P, visited by ESA's robotic Rosetta spacecraft, bolsters this hypothesis. Pictured when climbing a road up to Teide National Park in the Canary Islands of Spain, a bright triangle of zodiacal light appeared in the distance soon after sunset. Captured on June 21, 2019, the scene includes bright Regulus, the alpha star of the constellation Leo, standing above center toward the left. The Beehive Star Cluster (M44) can be spotted below center, closer to the horizon and also immersed in the zodiacal glow.
