[漢羅] 瑞士 ê Alps 山，火星 ê 天空

這張是 tī 2 月 6 號翕 ê。這个白雪雪 ê 山頭是 tī 地球瑞士中部 ê Melchsee-Frutt 附近。這个 tī 下晡反紅 ê 天色 kah 反藍 ê 日光，kah 火星 ê 天色 仝款。當然，兩个世界 攏是仝一粒太陽。Ùi 火星來看，太陽看起來 kan-na 有 tī 地球看起來 ê 一半光，寸尺嘛 kan-na 賰三份二。Tī 火星表面足細粒 ê 塗粉粒 to̍h 浮 tī 火星薄薄 ê 大氣層內底，這 to̍h 是 kā 火星變紅 ê 氧化鐵。In 會吸收藍光，所以 火星 ê 天空 才會反紅。毋閣，tī 較細粒、較暗 ê 火星太陽附近，向前行 ê 散射猶是會 kā 太陽光變較藍淡薄仔。一般來講，地球厚厚 ê 大氣層會大力散射藍光，所以天空才會是藍色 ê。毋閣 tī  2 月 6 號，有 足厚 ê 塗粉雲 ùi Sahara 沙漠，吹過地中海，來到瑞士 ê Alps 山，kā 太陽變暗。予這下晡 ê 天色，變甲 kah 火星 ê 天空仝款。隔轉工，to̍h 賰白雪崁 tī 紅色 ê 沙塗面頂矣！

[English] Swiss Alps, Martian Sky 

Taken on February 6 ,this snowy mountain and skyscape was capturednear Melchsee-Frutt, central Switzerland, planet Earth.The reddish daylight and blue tinted glow around the afternoon Sun are colors of the Martian sky , though.Of course both worlds have the same Sun.From Mars, the Sun looks only about half as bright and 2/3 the sizecompared to its appearance from Earth.Lofted from the surface of Mars, fine dust particles suspendedin the thin Martian atmosphere are rich in the iron oxides that makethe Red Planet red.They tend to absorb blue sunlight giving a red tinge to the Martian sky ,while forward scattering still makes the lightappear relatively bluish near the smaller, fainter Martian Sun.Normally Earth's denser atmosphere strongly scatters blue light, makingthe terrestrial sky blue.But on February 6 a huge cloud of dust blown across the Mediterraneanfrom the Sahara desert reached the Swiss Alps, dimming the Sun andlending that Alpine afternoon the colors of the Martian sky.By the next day, only the snow was left covered with reddish dust.
