[漢羅] 月圓 kah 藍色目屎

啥物物件 tī 暗暝會發光？ 這幅 夜景相片內底，有四常 ê 光 kah 無四常 ê 光。 四常 ê 光應該就是 月光，是咱熟似 ê 天體。 因為觀測者是 tī 地球赤道 附近，所以月娘是 直直沉落去。 月娘沉落去了後，地球大氣 內底 ê 空氣 kah 煙霧質 會散射藍光，予 反射日光 ê 衛星 tī 地平線附近看起來較紅。 無四常 ê 光 應該就是 浮游生物 發--出 ê 生物光，是咱較無熟似 ê 物件。 這寡 微生物 會發出藍光，應該是欲 嚇驚 捕食者。 像這个例，生物光主要是 綴 海湧咧泅 ê 浮游生物，tī 海岸去予拍散去，才會發光--ê。 這張相片是舊年 tī Maldives ê Soneva Fushi 島 翕--ê。

[English] A Full Plankton Moon

What glows in the night? This night featured a combination of usual and unusual glows. Perhaps the most usual glow was from the Moon, a potentially familiar object. The full Moon's nearly vertical descent results from the observer being near Earth's equator. As the Moon sets, air and aerosols in Earth's atmosphere preferentially scatter out blue light, making the Sun-reflecting satellite appear reddish when near the horizon. Perhaps the most unusual glow was from the bioluminescent plankton, likely less familiar objects. These microscopic creatures glow blue, it is thought, primarily to surprise and deter predators. In this case, the glow was caused primarily by plankton-containing waves crashing onto the beach. The image was taken on Soneva Fushi Island, Maldives just over one year ago.
