[漢羅] 光 kah 厚塗粉 ê 夜空

金星是暗暝上光 ê 天星。 Tī 南半球早春 ê 暗暝，金星會出現 tī 西爿地平線附近。 為著欲創作這幅組合景色，翕相 ê 人 tī 9 月 25 踮巴西南部 ê Cascavel 用追蹤天景 kah 固定前景 ê 方式感光。 日落了後，金星 to̍h 出現矣。 伊浸 tī 黃道光 ê 光錐內底，太陽光 to̍h ùi 太陽系黃道面 內底 ê 塗粉散射--出來。 實際上，毋管是 tī 地球北半球抑是南半球，黃道光 ê 光弧若是 kah 地平線 切 ê 角度傷崎，伊 tī 春分彼陣日落了後（抑是秋分彼陣日出進前）to̍h 會變足明顯 ê。 日落了後 ê 暗暝，黃道光射 tùi 厚恆星 ê 星場 kah 銀河中心彼个有巨型星際塗粉雲 ê 核球。 Ùi 銀河中心 ê 核球 行 tùi 銀河 tī 地平線 ê 方向，你 to̍h 會看著離太陽上近 ê 恆星系統，半人馬座 α。 伊離咱 kan-na 4.37 光年遠爾爾。

[English] A Light and Dusty Night

Posing as a brilliant evening star, Venus lies near the western horizon in this southern hemisphere, early spring, night skyscape. To create the composite view exposures tracking the sky and fixed for the foreground were taken on September 25 from Cascavel in southern Brazil. In view after sunset, Venus appears immersed in a cone of zodiacal light, sunlight scattered from dust along the Solar System's ecliptic plane. In fact from either hemisphere of planet Earth, zodiacal light is most visible after sunset near a spring equinox, (or before sunrise near an autumn equinox) when its luminous arc lies at steep angles to the horizon. Extending above the sunset on this night, the zodiacal light reaches toward rich starfields and immense interstellar dust clouds in the bulge of the central Milky Way. Follow along the Milky Way from the central bulge back toward the horizon and you'll spot the closest star system to the Sun, Alpha Centauri, a mere 4.37 light-years away.
