[漢羅] 黃道光 kah 火星

三月 7 號日頭落山了後，tī Illinois 田庄仔 ê 夜空，有一條若有若無 ê 光帶猶閣 tī 這幅圖 ê 西爿 ê 地平線面頂。 這張相片是 tī 一个老農村翕--ê。 彼搭較光 ê，是黃道光。 Tī 地球北半球春天 ê 時陣，等日頭落山了後，to̍h tī 西爿看會著。 Tī 這个晴和 ê 暗暝，這條黃道光，敢若欲 kā 火星 kah 昴宿星團食去。 In to̍h tī 這間囥粟仔 ê 舊倉庫厝頂，這个天星滿滿是 ê 夜空 相拄。 黃道光是太陽光 tī 太陽系黃道面內底，去予星際塗粉粒 kā 散射造成 ê。 當然，太陽系 ê 行星攏行 tī 黃道面 附近，to̍h tī 黃道光帶內底。 毋過，黃道光 kah 火星可能足有關係 ê。 最近有一台 ùi 地球飛去 木星 ê Juno 太空船。 用伊提著 ê 星際塗粉 ê 資料 來 kā 分析，發現產生黃道光 ê 塗粉，可能是 ùi 火星來 ê。

[English] Zodiacal Light and Mars

Just after sunset on March 7, a faint band of light still reaches above the western horizon in this serene, rural Illinois, night skyscape. Taken from an old farmstead, the luminous glow is zodiacal light, prominent in the west after sunset during planet Earth's northern hemisphere spring. On that clear evening the band of zodiacal light seems to engulf bright yellowish Mars and the Pleiades star cluster. Their close conjunction is in the starry sky above the old barn's roof. Zodiacal light is sunlight scattered by interplanetary dust particles that lie near the Solar System's ecliptic plane. Of course all the Solar System's planets orbit near the plane of the ecliptic, within the band of zodiacal light. But zodiacal light and Mars may have a deeper connection. A recent analysis of serendipitous detections of interplanetary dust by the Juno spacecraft during its Earth to Jupiter voyage suggest Mars is the likely source of the dust that produces zodiacal light.
